2 joules of work is done in displacing a stone through 0.5 m. Find the force applied on the stone.

Text Solution

Verified by Experts

Given work, W = 2 J
Displacement, s = 0.5 m
W = F `xx` s
2 J = F `xx` 0.5 m
`therefore F = (2)/(0.5) = 4 N`

20 J work is required to stretch a spring through 0.1 m . Find the force constant of the spring. If the spring is further stretched through 0.1 m. Calculate work done.

Assertion , No work is done if the displacement is zero Reason: Work done by the force is defined to be the product of component of the force in the the direction of the displacement and the magnitude of displacement.

Mathematically, work is defined as the product of froce and displacement through which force acts. If F is the applied force, 'S' is the displacement in the direction of applied force and W is the work done, then : Work done = Force xx Displacement through which force acts. W = F xx S The SI unit of work is Joule (J) and cgs unit is erg. 1 J = 10^(7) erg. You and your friends apply a combined force of 800 N to push a stone. The amount of work done is 3200 J. What distance did the stone move ?
