(4 x^{2} + 3 x) N

acts on a particle which displaces it from

x = 2 m

x = 3 m

. Te work done by the force is:

(4 x^{2} + 3 x) N

acts on a particle which displaces it from

x = 2 m

x = 3 m

. The work done by the force is:

\to F = (3 x^{2} + 2 x - 7) N

acts on a 2 kg body as a result of which the body gets displaced from x=0 to x=5m. The work done by the force will be-

F = (2 x + 3 x^{2}) N

acts on a particle in

x -

direction, where

F

is in Newton and

x

is in metre. Find the work done by this force for the displacement from

x = 0 m

x = 3 m

.

F = (10 + 0.5 x) N

acts on a particle in

X

direction, where
