Answer :
Work is said to be done when the displacement of the object is in the direction of the applied force. Its dimension formula is [ML²T⁻²].
Work is defined as the product of force vector and displacement vector. It is a scalar quantity. The work on an object is said to be done when the object gets displaced to a certain distance in the direction of the applied force.
W = F × d × Sinθ
Where F is the force, d is the distance, θ is the angle between the force and the distance. Its dimension formula is [MLT⁻²] × [L] = [ML²T⁻²]. Hence the correct option is b.
