NEET Physics Newton's Laws MCQ Question
A block of mass 5 kg is placed on a frictionless horizontal surface. A force of 20 N is applied horizontally. What is the acceleration of the block?
4 m/s²
5 m/s²
2 m/s²
6 m/s²
Correct Answer
Detailed Explanation
Using Newton's second law, F = ma, where F is the force applied (20 N) and m is the mass (5 kg). Solving for acceleration, a = F/m = 20/5 = 4 m/s².
