The bob of a simple pendulum has mass $2 g$ and a charge of $5.0 μ C .$ It is at rest in a uniform horizontal electric field of intensity $2000 V / m$ At equilibrium, the angle that the pendulum makes with the vertical is:
$(t a k e g = 10 m / s^{2})$

Options:

Answer:

Solution:

$\tan θ = \frac{Q E}{m g} = \frac{5 \times 10^{- 6} \times 2000}{2 \times 10^{- 3} \times 10} = \frac{1}{2}$
$\Rightarrow θ = \tan^{- 1} (0.5)$
