Q1 If work done in moving a change of50mcfrom infinity
to a point O in an electric field is 20J,then what
is the electric potential of ths point?
(a) 250V (b) 750V
(c) 400V (c) 450V
In question 1 also tell me the full frm of

Dear Student,
We know that V=W/q so V=20/50 milli coulomb

So V=20/50 milli coulomb

So V= 20 x 1000/50 = 400 V

Here "mc" stands for milli coulomb

Regards
