Since points A and B lie on the same equipotential surface, the potential difference between them is zero. Work done in moving a charge across an equipotential surface is given by: W = qΔV Since ΔV = 0, the ...
Since the charge is at the center of the square, the potential at all corners is the same. Moving a charge between two points at the same potential requires no work because the potential difference is zero. Thus, the correct ...
The energy stored in a capacitor is given by U = (1/2) C V². The decrease in energy is given as 2 × 10⁻² J. Substituting initial capacitance 2 µF, voltage 200 V, and solving for X, we get X ...
The equivalent capacitance of capacitors in series is given by the reciprocal formula. For 2 pF, 3 pF, and 6 pF in series, the calculation results in 1 pF. Hence, the correct answer is 1µF (option b). Class 12th Science ...
