Type: MCQ-numerical-Easy-Class 11
A body of mass 10 kg is initially at rest on a smooth horizontal surface. If a constant force of 20 N is applied horizontally, what is the acceleration of the body?
A
1 m/s²
B
2 m/s²
C
5 m/s²
D
10 m/s²
Correct Answer
Option B
Detailed Explanation
Using Newton's Second Law, F = ma, the acceleration a = F/m = 20 N / 10 kg = 2 m/s².
