When three forces of $50 \,N, 30\, N $ and $15\,N$ act on a body, then the body is

AAt rest

BMoving with a uniform velocity

CIn equilibrium

DMoving with an acceleration

Solution

(d)Here all the three force will not keep the particle in equilibrium so the net force will not be zero and the particle will move with an acceleration.

(AIPMT-1996)

A block of mass $2\,kg$ moving on a horizontal surface with speed of $4\,ms ^{-1}$ enters a rough surface ranging from $x =0.5\,m$ to $x =1.5\,m$. The retarding force in this range of rough surface is related to distance by $F =- kx$ where $k =12\,Nm ^{-1}$. The speed of the block as it just crosses the rough surface will be ……….. $\,ms ^{-1}$
