Solution

The correct option is B False
No,
When a body is lifted the force of gravity is acting in the downward direction. But, the displacement of the body is in the upward direction. Since the angle between the force and displacement is $0^{0}$ .
We know
W $= F \times S \times c o s θ$
So, the Work done will be positive .

The sign of work done by a force on a body is important to understand. State carefully if the following quantities are positive or negative:

(a) work done by a man in lifting a bucket out of a well by means of a rope tied to the bucket.

(b) work done by gravitational force in the above case,

(d) work done by an applied force on a body moving on a rough horizontal plane with uniform velocity,

(e) work done by the resistive force of air on a vibrating pendulum in bringing it to rest.

When force applied is not in the direction of displacement of an object, is there any work done?

Why work is said to be negative when force is applied opposite to the direction of displacement?
