Option B

Option C

Option D

Solution

To bring stationary object in motion force is required. Similarly to slow down object in motion or to stop moving object force is required.

A ball is moving down along slope. By applying force in opposite direction it can be stopped. The external parameter (agency) by which can change state of motion or rest can be changed is called force.

Effect of force on a body can be following :

$(i)$ Force can bring body in rest to motion or body in motion to rest.

$(ii)$ It can increase or decrease speed of object.

$(iii)$ Force can change direction of motion of object.

$(iv)$ Force can change shape of an object.

A piece of wire is bent in the shape of a parabola $y=k x^2$ ( $y$-axis vertical) with a bead of mass $m$ on it. The bead can slide on the wire without friction. It stays at the lowest point of the parabola when the wire is at rest. The wire is now accelerated parallel to the $x$-axis with a constant acceleration $\alpha$. The distance of the new equilibrium position of the bead, where the bead can stay at rest with respect to the wire, from the $y$-axis is

Three force $F_1=10\,N , F_2=8\,N , F _3=6\,N$ are acting on a particle of mass $5\,kg$. The forces $F _2$ and $F _3$ are applied perpendicular so that particle remains at rest. If the force $F_1$ is removed, then the acceleration of the particle is $……ms^{-2}$
