STANDARD Physics Force and Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
A body under the action of a force F = 6î - 8ĵ N acquires an acceleration of 5 m s⁻². The mass of the body is
A
2 kg
B
5 kg
C
4 kg
D
6 kg
Correct Answer
Option A
Detailed Explanation
The magnitude of the force is F = √((6)² + (-8)²) = 10 N. Using F = ma, the mass m = F/a = 10 N / 5 m s⁻² = 2 kg.
