Question

Statement A: If the force varies with time then the net force is measured by the total change in momentum of the body.
Statement B: Change in momentum and impulsive force are numerically equal.
  1. A & B are correct
  2. A & B are wrong
  3. A is correct and B is wrong
  4. A is wrong and B is correct

A
A & B are wrong
B
A is correct and B is wrong
C
A is wrong and B is correct
D
A & B are correct
Solution
Verified by Toppr

Force is a rate of change of momentum.
Force is measured as rate of change of momentum. It is not equal to change of momentum.
F=dMdt or, Fdt=dM
Impuse of force, J=Fdt=dM
Hence, Change in momentum and impulsive force are numerically equal.
A is wrong and B is correct.
