Problem

Two points

A

and

B

are 2 cm apart and a uniform electric field

E

acts along the straight line

AB

directed from

A

B

with

E = 200 \text{ N/C}

. A particle of charge

+10^{-6} \text{ C}

is taken from

A

B

along

AB

. Calculate (a) the force on the charge (b) the potential difference

V_A - V_B

and (c) the work done on the charge by

E
