Kinematics Question 114
Question: A force (where K it’s a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x- axis to the point (a, 0) and then parallel to the y-axis to the point (a, a). The total work done by the forces on the particle is [IIT-JEE 1998]
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
For motion of the particle from (0, 0) to (a, 0)
Displacement
So work done from (0, 0) to (a, 0) it’s given by
For motion (a, 0) to (a, a)
So work done from (a, 0) to (a, a)
So total work done
