Question

To bring up a particle of charge 20mewC from infinity to a point P, the total work 2.0mJ is done by internal forces. What is the potential at point P

Answer 1

to bring of a particular of charge 20 m is he from infinity to a point P the total work too. Omitted is done by internal force what is the professional at point P I don't know the answer of this question so you can ask from anyone please

Answer 2

Answer:

given,

q= 10 millicoulomb

or q= 10 x 10^-6 coulomb

w= 2.0 mJ

or w= 2 x 10^-3 joules

potential at point P = v= w/q

= 2 x 10^-3/ 10 x 10^6

= 2 x 10^2 v

therefore, potential at point P = 200v
