A) zero
B) 5\[({{F}_{s}}=\mu R)\]C
C) 10\[W=\mu mgd\cos \theta \]C
D) 25\[(R=mg)\]C
Correct Answer: C
Solution :
We know that capacitor offers infinite resistance for DC source. (Battery is DC source) Current taken from the cell \[W=MB(1-\cos \theta )\] \[={{10}^{4}}\times 4\times {{10}^{-5}}(1-\cos {{60}^{o}})\] Potential drop across capacitor \[=0.2J\] \[L=10H,R=5\Omega ,e=5v\] The current in 2 0 resistor is zero. Charge on capacitor \[t=2\] \[I={{I}_{0}}(1-{{e}^{-Rt/L}})\] \[I=\frac{E}{R}(1-{{e}^{-RT/L}})\]You need to login to perform this action.
