Question asked by Filo student

3) decreases, decreases of radius ' $R$ ' carrying a charge ' $Q$ ' is joined to an uncharge sphere of radius $2R$. The charge flow between them will be 3) $Q^2$ i) $Q/4$ 2) $Q/3$ 126. A capacitor of capacity ' $C$ ' is charged. 2) $1/9$ 1) $1/3$ 127. Consider the following statements (A) : The capacity of the earth is infinity (B) : The potential of the earth is zero 2) $A\&R$ are false 1) $A$ \& $B$ are true 3) $A$ is true, B is false 128. A condenser of capacity $2\mu \mathrm{F}$ is charged to a potential of condenser of capacity $3\mu \mathrm{F}$. The common potential is 3) $80\mathrm{V}$ 2) $100\mathrm{V}$ 4) $50\mathrm{s}$
