As per analysis for previous years, it has been observed that students preparing for NEET find Physics out of all the sections to be complex to handle and the majority of them are not able to comprehend the reason behind it. This problem arises especially because these aspirants appearing for the examination are more inclined to have a keen interest in Biology due to their medical background.

Furthermore, sections such as Physics are dominantly based on theories, laws, numerical in comparison to a section of Biology which is more of fact-based, life sciences, and includes substantial explanations. By using the table given below, you easily and directly access to the topics and respective links of MCQs. Moreover, to make learning smooth and efficient, all the questions come with their supportive solutions to make utilization of time even more productive. Students will be covered for all their studies as the topics are available from basics to even the most advanced.

Q1. The time period of geostationary satellite at a height 36000 km is 24 h. A spy satellite orbits earth at a height 6400km. What will be the time period of sky satellite? (Radius of earth = 6400 km )
•  5 h
•  4 h
•  3 h
•  12 h
Solution

Q2.The acceleration to gravity at a height 1/20th of the radius of the earth above the earth surface is 9ms-2. Its value at a point at an equal distance below the surface of the earth in ms-2 is about below the surface of the earth in ms-2 is about
•  8.5
•  9.5
•  9.8
•  11.5
Solution

Q3.  33. Two satellite A and B go round a planet orbits having radii 4R and R, respectivly. If the speed of satellite A is 3v, then speed of satellite B is
•   3v2
•  4v2
•  6v
•  12v
Solution
Q4. An asteroid of mass m is approaching earth, initially at a distance of 10 Re with speed vi. It hits the earth with a speed vf (Re and Me are radius and mass of earth), then
•  vf2=vi2+2GmMeR1-110
•  vf2=vi2+2GMeRe1+110
•  vf2=vi2+2GMeRe1+110
•  vf2=vi2+2GmRe1-110
Solution

Q5.The distance of a geo-stationary satellite from the centre the earth (Radius R=6400 km) is nearest to
•  5 R
•  7 R
•  10 R
•  18 R
Solution
6R from the surfaceo of earth and 7R from the centre.

Q6. A satellite moves in elliptical orbit about a planet. The maximum and minimum velocities of satellites are 3×104ms-1 and 1×103ms-1 respectively. What is the minimum distance of satellite from planet, if maximum distance is 4×104 km?
•  4*103Km
•  3*103 Km
•  4/3 * 103 Km
•  1*103 Km
Solution

Q7.Assuming earth to be a sphere of radius R, if g30° is value of acceleration due to gravity at latitude of 30° and g at the equator, the value of g-g30°is
•  142R
•  342R
•  2R
•  122R
Solution

Q8.Two satellites of earth, S1 and S2, are moving in the same orbit. The mass of S1 is four times the mass of S2. Which one of the following statements is true?
•  The time period of S1 isfour times that of S2
•  The potential energies of earth and satellite in the two cases are equal
•  S1 and S2 are moving with the same speed
•  The kinetic energies of the two satellites are equal
Solution
Q9.The ratio of acceleration due to gravity at a height h above the surface of the earth and at a depth h below the surface of the earth for h< < radius of earth
•  Is constant
•  Increases linearly with h
•  Decreases linearly with h
•  Decreases parabolically with h
Solution Q10. The weight of an object in the coal mine,sea level, at the top of the mountain are W1,W2 and W3 respectively , then
•  W1W3
•  W1=W2=W3
•  W1
•  W1>W2>W3
Solution
Because value of g decreases when we move either in coal mine or at the top of mountain ## Want to know more
