MCQ
Assertion (A): The Work-Energy theorem is applicable for non-inertial frames also.
Reason (R): The Work-Energy theorem is applicable to non-inertial frames provided we include the pseudo forces in the calculation of the net force acting on the body under consideration.
  • A
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • D
    A is false but R is true.

Answer

(a) Both A and R are true and R is the correct explanation of A .
Explanation: The Work-Energy theorem is applicable for non-inertial frames. The assertion is true.
If we include the pseudo forces in the calculation of the net force acting on the body under consideration then this theorem is applicable for the non-inertial frame also.
The assertion and reason both are true and the reason also explains the assertion.
