An electron starting from rest has a velocity that increases linearly with the time that is \dot{\nu} = kr. where k = 2m/sec^2 . The distance travelled in the first 3 seconds will be
Text Solution
Verified by ExpertsThe correct answer is:
A
\(s = \int_0^3 v \, dt = \int_0^3 kt \, dt = \left| \frac{1}{2} kt^2 \right|_0^3 = \frac{1}{2} \times 2 \times 9 = 9 \, m\)
