A) \[\frac{mg}{\sin \theta }\] and \[\frac{qE}{\cos \theta }\]
B) \[\frac{mg}{\cos \theta }\] and \[\frac{qE}{\sin \theta }\]
C) \[\frac{qE}{mg}\]
D) \[\frac{mg}{qE}\]
Correct Answer: B
Solution :
A pendulum bob of weight mg and carrying a charge q is suspended in the electric field E. Suppose that it comes to rest at point A, so that it makes an angle \[\theta \] with the vertical as shown. At point A, the bob is acted upon by the following three forces.You need to login to perform this action.
