Work done in placing a charge of 8 x 10-18C on a condenser of capacity...
Given data:
Charge, q = 8 × 10⁻¹⁸C
Capacitance, C = 100 μF = 100 × 10⁻⁶F
Formula used:
The work done in charging a capacitor is given by the formula:
W = (1/2)CV²
where V is the potential difference across the capacitor.
Calculation:
The charge on the capacitor is given by:
q = CV
⇒ V = q/C
Substituting the given values, we get:
V = (8 × 10⁻¹⁸C) / (100 × 10⁻⁶F) = 8 × 10⁻¹⁴V
The work done in charging the capacitor is given by:
W = (1/2)CV²
Substituting the values of C and V, we get:
W = (1/2)(100 × 10⁻⁶F)(8 × 10⁻¹⁴V)² = 32 × 10⁻³²J
Therefore, the work done in placing a charge of 8 × 10⁻¹⁸C on a capacitor of capacitance 100 μF is 32 × 10⁻³²J.
Hence, option (B) is the correct answer.
