MCQ
The n rows each containing $m$ cells in series are joined in parallel. Maximum current is taken from this combination across an external resistance of $3\Omega$ resistance. If the total number of cells used are $24$ and internal resistance of each cell is $0.5\Omega$ then
  • A
    $m = 8, n = 3$
  • B
    $m = 6, n = 4$
  • ✓
    $m= 12, n = 2$
  • D
    $m = 2, n = 12$
✓

Answer

Correct option: C.
$m= 12, n = 2$

The density of a rod gradually decreases from one end to the other. It is pivoted at an end so that it can move about a vertical axis through the pivot. A horizontal force F is applied on the free end in a direction perpendicular to the rod. The quantities, that do not depend on which end of the rod is pivoted, are:
  1. Angular acceleration.
  2. Angular velocity when the rod completes one rotation.
  3. Angular momentum when the rod completes one rotation.
  4. Torque of the applied force.
