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. Weight of 1kg becomes 1/6 on moon. If radius of moon is 1.768×106 m, then the mass of moon will be
•  1.99×1030kg
•  7.56×1022kg
•  5.98×1024kg
•  7.65×1022kg
Solution

Q2.A satellite of mass m is placed at a distance r from the centre of earth (mass M). The mechanical energy of the satellite is
•  -GMmr
•  GMmr
•  GMm2r
•  -GMm2r
Solution

Q3.  13. A satellite S is moving in an elliptical orbit around earth. The mass of the satellite is very small compared to the mass of the earth?
•   The acceleration of S is always directed towards the centre of the earth
•  The angular momentum of S about the centre of the earth changes in direction but its magnitude remains constant
•  The total mechanical energy of S varies periodically with time
•  The linear momentum of S remains constant in magnitude
Solution

Q4. The escape velocity of a body on the surface of the earth is 11.2 km/s. If the earth’s mass increases to twice its present value and the radius of the earth becomes half, the escape velocity would become
•  5.6 Km/s
•  11.2 km/s(remain unchanged)
•  22.4 Km/s
•  44.8 Km/s
Solution

Q5.A geostationary satellite is orbiting the earth at a height of 5R above the surface of the earth, R being the radius of the earth. The time period of another satellite in hours at a height of 2R from the surface of the earth is
•  5
•  10
•  62
•  62
Q6. The escape velocity of a sphere of mass m from earth having mass M and radius R is given by
•  2GMR
•  2GMR
•  2GMmR
•  GMR
Solution
Escape velocity does not depend on the mass of the projectiles

Q7.Gravitational potential on the surface of earth is (M=mass of the earth, R= radius of earth)
•  -GM/2R
•  -gR
•  gR
•  GM/R
Solution

Q8.18. If orbital velocity of planet is given by v=GaMbRc, then
•  a=1/3, b=1/3, c=-1/3
•  a=1/2, b=1/2, c=-1/2
•  a=1/2, b=-1/2, c=1/2
•  a=1/2, b=-1/2, c=-1/2
Solution
The system will be bound at points where total energy is negative. In the given curve at point A, B and C the P.E. is more than K.E.

Q9.If both the masses and radius o the earth, each decreases by 50%, the acceleration due to gravity would
•  Remain same
•  Decrease by 50%
•  Decrease by 100%
•  Increase by 100%
Solution Q10. A spherical planet for out in space has a mass M0 and diameter D0. A particle of mass m falling freely new the surface of this planet will experience an acceleration due to gravity which is equal to
•  GM0/D02
•  4mGM0/D02
•  4GM0/D02
•   GmM0/D02
