A) \[\frac{\text{mg}}{\text{sin}}\text{and}\frac{\text{qE}}{\text{cos}\,}\]
B) \[\frac{\text{mg}}{\text{cos}}\text{and}\frac{\text{qE}}{\sin \,}\]
C) \[\frac{\text{qE}}{mg}\]
D) \[\frac{mg}{\text{qE}}\]
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.
