One joule work is said to be done when :
A. a force of 1 N displaces a body by 1 cm
B. a force of 1 N displaces a body by 1 m
C. a force of 1 dyne displaces a body by 1 m
D. a force of 1dyne displaces a body by 1 m
SI unit of work is joule which is denoted by J.
1 joule = 1 newton×1 meter
1 J = 1 Nm
1 joule of work is said to be done when a force of 1 Newton moves an object through a distance of 1 meter in direction of force.
