19) Differentiate elastic lastit toll20) Calculate the work done by a force of 30N in lifting a load of 2kg to Ă fileigriof 10m (g 10ms2).igh hetween stable and unstable equilibrium?

Answer»

Given: force = 30N

displacement = 10m

We know that, Work done = Displacement × Force

Work done = 30 * 10

= 300 Joule
