Questions
A body of mass 2 kg is placed on a smooth horizontal surface. Two forces are acting on the body in directions making angle of and to the surface. The reaction of the surface on the body will be
detailed solution
Correct option is D
N+F1Sin300+F2Sin600= mg⇒ N+20×12+103.32=20⇒ N = 20−25 = −5Normal reaction is coming negative means the body is lifted from the ground and hence N = 0Similar Questions
