Question

A body undergoes a displacement of two ICAP metre in the force 3 j cap Newton what is the work done by the force

Answer 1

Displacement = 2î metres

Force = 3j cap Newton

Work = Force . Displacement

=>2î.3jcap

=>0

{cause dot product of î and j cap is 0}

{also, the ∅ is 90° so, it makes the cos90 = 0 }

Cheers!

Answer 2

Answer:

work done is zero because cos90 is zero
