Explanation / Answer

a)

Va = (9 x 109) (6.2 x 10-6) /5 = 11160 Volts

Vb = (9 x 109) (6.2 x 10-6) /5 = 11160 Volts

Q = charge on proton = 1.6 x 10-19

Wab = Work done = Q (Vb - Va) = (1.6 x 10-19) (11160 - 11160) = 0 J

b)

since C and D are at same distance from charge at origin , hence Vc = Vd

Wcd = Work done = Q (Vd - Vc) = 0 J

c)

Vc = (9 x 109) (6.2 x 10-6) /sqrt(52 + 52) = 7891.31 Volts

Va = 11160 Volts

Wca = Work done = Q (Va - Vc) = (1.6 x 10-19) (11160 - 7891.31) = 5.23 x 10-16 J

d)

Vd = (9 x 109) (6.2 x 10-6) /sqrt(52 + 52) = 7891.31 Volts

Vb = 11160 Volts

Wdb = Work done = Q (Vb - Vd) = (1.6 x 10-19) (11160 - 7891.31) = 5.23 x 10-16 J
