A) \[2:1\]
B) \[1:2\]
C) \[1:4\]
D) \[4:1\]
Correct Answer: B
Solution :
Using \[V=\sqrt{\frac{2QV}{m}}\] (as, \[QV=\frac{1}{2}\,m{{V}^{2}}\]) \[V\propto \,\,\sqrt{Q}\] \[\frac{{{V}_{A}}}{{{V}_{B}}}=\sqrt{\frac{{{Q}_{A}}}{{{Q}_{B}}}}=\sqrt{\frac{q}{4q}}=\frac{1}{2}\]You need to login to perform this action.
