In a uniform electric field, a point charge of mass m and charge q is released from rest. If there are no other forces acting on the particle, then which of the following graphs, correctly show the dependence of the particles speed v on the distance x travelled by the particles speed v on the distance x travelled by it? [Graphs are schematic and not drawn to scale]

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
Using work - energy theorem. `qEx=(1)/(2)mv^(2)implies upsilon^(2)=(2qE)/(m)x` `implies upsilon=sqrt((2qE)/(m))sqrt(x)`
