A body having specific charge 
is resting on a frictionless plane at a distance 10cm from the wall (as shown in the figure). It starts moving towards the wall when a uniform electric field of 100V/m is applied horizontally towards the wall. If the collision of the body with the wall is perfectly elastic, then the time period of the motion will be ___ s.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(1)
F = ma
qE = ma
Now 
Time period = 2t=1sec
