Figure D shows two spheres that initially have +4 and +8 positive charge. After an interaction (which could simply be that they touch each other), the yellow sphere has +10 positive charge, and the red sphere has an unknown quantity of charge. Use the law of conservation of charge to find the final charge on the red sphere.

Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact. (a) What is the new charge on each sphere? (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?

Two metallic spheres of radii 1 cm and 2 cm are given charges 10^(-2) C and 5 xx 10^(-2) C respectively. If they are connected by a conducting wire, the final charge on the smaller sphere is

There are two spheres of radii R and 2R having charges Q and Q//2 , respectively. These two spheres are connected with a cell of emf V volts as show in. When the switch is closed, find the final charge on each sphere.

Consider three identical metal spheres A, B and C . Sphere A carries charge + 6q , sphere B carries charge -3q and sphere C carries no charge . Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it . Finally the sphere C is touched to sphere B and separated from it . Find the final charge on the sphere C .

A large hollow metallic sphere has a positive charge of 35.4muC at its centre. Find how much electric flux emanates from the sphere.

Two identical conducting spheres are charged by induction and then separated by a large distance, sphere 1 has charge +Q and sphere 2 has charge -Q. A third sphere is initially uncharged. If sphere 3 is touched to sphere 1 and separated and then touched to sphere 2 and separated what is the final charge on each of the three spheres?

Assertion : When two charged spheres are connected to each other by a thin conducting wire, charge flow bigger sphere to smaller sphere, if initial charges on them are same. Reason : Electrostatic potential energy will be lost in redistribution of charges.
