Question

10.
Two spheres of radii R1 . and R2 . have equal charge are joint together with a copper wire. If v is potential on
each sphere after they are separated to each other, then initial charge on any sphere was​

Answer 1

Answer:

V(r1+r2)/2k

Explanation:

Q1=c1v

Q1=vr1/k

Q2=c2v

Q2=r2v/k

Q=Q1+Q2

Q=v(r1+r2)/k

For single sphere

Q/2=v(r1+r2)/2k
