(A) the common potential will be 20V (B) the final charges of capacitors will be 100muC and 200muC (c) the ratio of total energy stored in capacitors before and after connection is 3:2 (D) the loss energy of system is 1500muJ

Eight charges, 1muC, -7muC , -4muC, 10muC, 2muC, -5muC, -3muC, and 6muC , are situated at the eight cornersof a cube of side 20 cm. A spherical surface of radius 80 cm encloses this cube. The center of the sphere coincides with the center of the cube. Then, the total outgoing flux from the spherical surface (in units of Vm) is

Three parallel plate capacitors C_(1) = 4 muF,C_(2) =2mu F,C_(3) = 6muF with respective charges q_(1) = 20 muC,q_(2) = 10 mu C,q_(3) =5 muC are connected in series with a battery of emf 10 V through an open switch as shown. Now the switch is closed and steady state is reached. .
