QAIPMT-2007-Ph-2363: NEET 2007 Physics - Class 12 AIPMT-2007-Ph-2363 Solution: A particle moving along x-axis has acceleration f at time t…

A particle moving along x-axis has acceleration f at time t given by

f = f_0(1-\frac{t}{T})

where

f_0

and T are constants. The particle at t = 0 has zero velocity. In the time interval between t = 0 and the instant when f = 0 the particle's velocity (

v_x

) is

\frac{1}{2}f_0T^2

f_0T^2

\frac{1}{2}f_0T

f_0T

Multiple Choice Options

A ${q \over {2{\varepsilon _0}}}$ 2 _ 0 _ q _
B ${\phi \over 3}$ 3 _ _
C ${q \over {{\varepsilon _0}}} - \phi$ _ 0 _ q _ _ _
D ${1 \over 2}\left( {{q \over {{\varepsilon _0}}} - \phi } \right)$ 2 1 _ ( _ 0 _ q _ _ _ )

Step-by-Step Verified Solution

Let _ A , _ B and _ C are the electric flux linked with A, B and C. According to Gauss theorem, _ A + _ B + _ C = q _ 0 Since _ A = _ C _ 2 _ A = q _ 0 _ _ B _ 2 _ A = q _ 0 _ _ ( G i v e n _ B = _ ) _ _ A = 1 2 ( q _ 0 _ _ )
