Displacement time graph of an object of ...

Displacement time graph of an object of mass 2kg is shown in figure. The force required to move the object for first four seconds is

A

0

B

4N

C

2N

D

8N

Text Solution

Verified by Experts

The correct Answer is:
A
The displacement time graph in the question is a straight line with a positive slope . It means object has uniform velocity and zero acceleration.
`therefore F=m times a= m times 0=0`
