Question

A body is projected from ground obliquely. During downward motion, power delivered by gravity to it (A) Increases (B) Decreases (C) Remains constant (D) First decreases and then becomes constant

Tardigrade Admin · Accepted Answer

Power =F v cos θ θ < 90° Velocity of particle will increase So power will increase as F is constant

Q. A body is projected from ground obliquely. During downward motion, power delivered by gravity to it

Increases

Decreases

Remains constant

First decreases and then becomes constant

Power $= F v cos θ$
$θ < 9 0^{\circ}$
Velocity of particle will increase
So power will increase as $F$ is constant

Increases

Decreases

Remains constant

First decreases and then becomes constant

Power =Fvcosθ θ<90∘ Velocity of particle will increase So power will increase as F is constant

Power $= F v cos θ$
$θ < 9 0^{\circ}$
Velocity of particle will increase
So power will increase as $F$ is constant
