Figure shows two conducting spheres separated by large distance and of radius 2 cm and 3 cm containing charges `10 muC` and `20 muC` respectively. When the spheres are connected by a conducting wire then find out following :
(i) Ratio of the final charge.
(ii) Final charge on each sphere.
(iii) Ratio of final charge densities.
(iv) Heat produced during the process.

Text Solution

Verified by Experts

The correct Answer is:
(i) `(Q'_(1))/(Q'_(2))=2/3`
(ii) `2/5xx30=12 muC, 3/5xx30=18 muC`
(iii) `(sigma'_(1))/(sigma'_(2))=3/2`
(iv) `2pi epsi_(0) ((r_(1)r_(2))/(r_(1)+r_(2))) (v_(1)-v_(2))^(2)=3//2` Joules
