Consider a circuit shown in the figure. The rod is free to slide over the resistanceless vertical rails. Maximum charge on the capacitor C is given by $q \times 1 0^{- 5}$ coulomb. Fill the value of q .

Answer:

3.00

Solution:

At equilibrium $m g = i ℓ B$

$m g = \frac{B v ℓ}{R} \times ℓ B$

$e = \frac{m g R}{ℓ B}$

$q_{m a x} = C Δ v = \frac{C \times m g R}{ℓ B}$

$= \frac{24 \times 1 0 ^{- 6} \times 0.1 \times 1 \times 10 \times 10}{8 \times ( 1 )}$

$= 3 \times 1 0^{- 5}$
