Question

$S_1$: The COM of a rod is at its geometrical centre. This means the rod is uniform.
$S_2$: The total potential energy of an electrostatic system may be positive.
$S_3$: The line integral of electric field over a closed loop drawn in a region having only a time varying magnetic field is zero.

• A. T T F
• B. T T T
• C. F T F
• D. F T T

Answer 1

The correct option is C F T F

The geometrical center of a body depends on the mass distribution. Mass distribution cannot be decided from the geometrical center of a body.
Potential energy of system can be positive,negative or zero.
Time varying magnetic field gives rise to a non-conservative electric field .
