Physics-Work Done by Forces
NEET Physics Work Done by Forces MCQ Question
Type: MCQ-numerical-Easy-Class 11
A body of mass 2 kg is initially at rest and moves under an applied horizontal force of 7 N on a table with a coefficient of kinetic friction of 0.1. Calculate the work done by the applied force in 10 seconds.
A
140 J
B
70 J
C
7 J
D
35 J
Correct Answer
Option A
Detailed Explanation
The work done by the applied force is calculated using W = F * d, where F is the applied force. In this case, the work done by the force is directly proportional to the time since the force is constant. The calculation uses the NCERT context of work done by an applied force.
