Question: 11

NEET 2013

In an experiment four quantities a, b, c and d are measured with percentage error 1%, 2%, 3% and 4% respectively. Quantity P is calculated as, $\displaystyle P=\frac{a^3b^2}{cd}$ . Error in P is

Question: 13

KEAM 2013

The percentage error in measuring M, L and T are 1%, 1.5% and 3% respectively. Then the percentage error in measuring the physical quantity with dimensions $ML^{-1}T^{-1}$ is

Question: 14

JEE MAIN 2012

Resistance of a given wire is obtained by measuring the current flowing in it and the voltage difference applied across it. If the percentage errors in the measurement of the current and the voltage difference are 3% each, then error in the value of resistance of the wire is

Question: 15

JEE ADVANCED 2012

In the determination of Young's modulus $\Bigg(\displaystyle Y = \frac{4MLg}{\pi l d ^ 2} \Bigg)$ by using Searle's method, a wire of length L = 2 m and diameter d = 0.5 mm is used. For a load M = 2.5kg, an extension l= 0.25 mm in the length of the wire is observed. Quantities d and l are measured using a screw gauge and a micrometer respectively. They have the same pitch of 0.5 mm. The number of divisions on their circular scale is 100. The contributions to the maximum probable error of the Y measurement is

The displacement of a particle moving along x-axis with respect to time t is $x = at + b t ^ 2 - c t ^ 3$. The dimensions of c are

Question: 17

KEAM 2012

If the time period of oscillation of a pendulum is measured as 2.5 second using a stop watch with the least count $\frac{1}{2}$ second, then the permissible error in the measurement is
