A) 1
B) \[\frac{1}{2}\]
C) \[{{r}_{1}}-{{r}_{2}}\]
D) \[{{r}_{1}}/{{r}_{2}}\]
Correct Answer: D
Solution :
We know that the potential for a metal sphere \[V=k\frac{q}{r}\] According to the question \[{{V}_{1}}=k\frac{{{q}_{1}}}{{{r}_{1}}}\] and \[{{V}_{1}}=k\frac{{{q}_{2}}}{{{r}_{2}}}\] as \[{{V}_{1}}={{V}_{2}}\] \[k\frac{{{q}_{1}}}{{{r}_{1}}}=k\frac{{{q}_{2}}}{{{r}_{2}}}\] \[\frac{{{q}_{1}}}{{{r}_{2}}}=\frac{{{r}_{1}}}{{{r}_{2}}}\]
