A) 1m
B) 2m
C) 1.5m
D) 3m
Correct Answer: D
Solution :
[d] Here, \[V=15\times {{10}^{6}}V\] dielectric strength \[=5\times {{10}^{7}}V{{m}^{-1}}\] Maximum electric field, E = 10% of dielectric strength As \[E=\frac{V}{r}\text{ }\therefore r=\frac{V}{E}=\frac{15\times {{10}^{6}}}{5\times {{10}^{6}}}=3m\]You need to login to perform this action.
