Solution

The correct option is A $2 m$
Mass of block = 2 kg
Force = 40 N
Suppose, the kinetic energy of the particle increases 40 J in a given interval of time.
We need to calculate the tension
Using balance equation
We need to calculate the displacement
Using work energy theorem
Put the value into the formula
Hence option A is correct
