## UNITS AND MEASUREMENTS QUIZ-2

JEE Advanced Physics Syllabus can be referred by the IIT aspirants to get a detailed list of all topics that are important in cracking the entrance examination. JEE Advanced syllabus for Physics has been designed in such a way that it offers very practical and application-based learning to further make it easier for students to understand every concept or topic by correlating it with day-to-day experiences. In comparison to the other two subjects, the syllabus of JEE Advanced for physics is developed in such a way so as to test the deep understanding and application of concepts.

•  -1/2, 1/2
Solution

Q3. The mass of the liquid flowing per second per unit area of cross section of the tube is proportional to Px and vy, where P is the pressure difference and v is the velocity, then the relation between x and y is
•  x = y
•  x = -y
•  y2 = x
•  y = -x2
Solution

Q4. The dimensional formula for resistivity of conductor is

Solution

Q6. The resistance of a metal is given by R=V/I, where V is potential difference and I is the current. In a circuit, the potential difference across resistance ,is V=(8 ± 0.5)V and current in resistance, I=(4 ± 0.2)â„«. What is the value of resistance with its percentage error?
Solution

Q7.
•  Wavelength
•  Volume
•  Pressure
•  Area
Solution

Q8. The percentage errors in the measurement of mass and speed are 2% and 3%, respectively. How much will be the maximum error in the estimation of KE obtained by measuring mass and speed?
•  5%
•  1%
•  8%
•  11%
Solution

Q9. Inductance L can be dimensionally represented as
•  M L2T-2A-2
•  M L2T-4A-3
•  M L-2T-2A-2
•  M L2T4A3
Solution

Q10. A student writes four different expressions for the displacement y in a periodic motion as a function of time t,a as amplitude, T as time period. Which of the following can be correct?
•
•
Solution
(d) Since L.H.S. is displacement, so R.H.S. should have dimensions of displacement. In (a), aT does not have the dimensions of displacement. Also the argument of a trigonometric function should be dimensionless. In (b), argument is not dimensionless and in (c), a/T does not have the dimensions of displacement. Hence, the correct choice is (d)
