A) \[\text{14}\text{.76 A}\]
B) \[\text{5}\text{.98 A}\]
C) \[\text{7}\text{.14 A}\]
D) \[\text{11}\text{.32 A}\]
Correct Answer: D
Solution :
For equilibrium, \[\text{mg sin30}{}^\circ \text{=I}l\text{B cos 30}{}^\circ \] \[\text{I=}\frac{mg}{l\text{B}}\tan 30{}^\circ \] \[=\frac{0.5\times 9.8}{0.25\times \sqrt{3}}=11.32\,\,\text{A}\]You need to login to perform this action.
