The correct answer is:(a) loses mass Explanation: When a body becomes positively charged, it loses electrons, which have a small mass. Although the mass loss is extremely tiny, it still occurs due to the removal of negatively charged electrons. Class ...
The correct answer is:(c) Gauss’s theorem can be applied to a non-uniform electric field. Explanation: Gauss’s law states that the total electric flux through a closed surface depends only on the net charge enclosed, regardless of the field’s uniformity. It ...
An electric dipole placed in a non-uniform electric field experiences both a force and a torque. The non-uniform field exerts unequal forces on the positive and negative charges, creating a net force. Additionally, torque aligns the dipole with the field ...
Using Ohm’s law: V=IR Given: V=200V, R = 100Ω Current: I = V/R = 200/100 =2A Charge flow in 1 second: Q = I × t = 2 × 1 = 2C Number of electrons: n = ...
