A body of mass `2.0kg` is pplaced on a smooth horizontal surface. Two force `F_(1)=20N` and `F_(2)=N` are acting on the body in directions making angles of `30^(@)` and `60^(@)` to the surface. The reaction of the surface om the body will be

A block of mass 2 kg is plased on a smooth horizontal surface. Two forces F_(1)=20 N and F_(2)=5 N start acting on the block in opposite directions as shown. If block gets displaced by 5 m in the direction of net force then work done by F_(2) is :-

A body of mass 5 kg is at rest on a smooth horizontal surface. A horizontal force 'F' acts on it for 4s and then ceases to act. If the body travels 40 m in the next 5s, the value of F is,

A force acts for 8 s on a body of mass 5kg at rest,on a smooth horizontal surface.The force then stops acting and the body describes 80m in next 5s .The force acting on body is ?

A body of mass M is kept on a rough horizontal surface (friction coefficient =μ). A person is trying to pull the body by applying a horizontal force but the body is not moving. The force by the horizontal surface on the surface of the body is F, where
