Q. A particle moves from a point

{\underset{r}{\to}}_{1} = (2 m) \underset{i}{\to} + (3 m) \underset{j}{\to}

to another point

{\underset{r}{\to}}_{2} = (3 m) \underset{i}{\to} + (2 m) \underset{j}{\to}

acts on it. Find the work done by the force on the particle during the displacement.

(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:

(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:

Q. A constant force

F = (^i + 3^j + 4^k) N

acts on a particle and displace it from

(- 1 m, 2 m, 1 m)

(2 m, - 3 m, 1 m)

. Then the work done by the force is:

Q. A force F acting on the particle varies with the position x as shown in figure. Find the work done by this force in displacing the particle from
(a) x = -2 m to x = 0
(b) x = 0 to x = 2m
