Solution

The correct option is A

1J


Step 1: Given data.

Mass of the particle, 2mg=2×10-3g

Distance, d=5m

Time, t=5s

Step 2: Finding the kinetic energy of the particle.

Formula used:

Kinetic energy, KE=12mv2

We know that,

Velocity, v=dt

v=55×10-3

v=103ms

Now,

KE=12mv2

KE=12×2×10-3×1032

KE=1J

Hence, option A is correct.
