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 ...
(c) electric intensity. The SI unit of electric field intensity (also called electric field strength) is Newton per Coulomb (N/C). It represents the force per unit charge experienced by a test charge in an electric field. Class 12th Science Physics ...
