Lorentz force is given by the following formula

A fighter plane is moving in a vertical circle of radius $r$. Its minimum velocity at the highest point of the circle will be

A body of mass $0.5 \,kg$ is projected under gravity with a speed of $98 \,m/s$ at an angle of $ 60^{\circ} $ with the horizontal. The change in momentum (in magnitude) of the body is

A body of mass $10 \,kg$ is moving with a constant velocity of $10 \,m/s$. When a constant force acts for $4 s$ on it, it moves with a velocity $2 \,m/s$ in the opposite direction. The acceleration produced in it is

The force constants of two springs are $ k_{1} $ and $ k_{2} $ respectively. Both are stretched till their potential energies are equal. The forces $ f_{1} $ and $ f_{2} $ applied on them are in the ratio

A body of mass $M$ is kept on a rough horizontal surface [friction coefficient $=u$). A person is trying to pull the body by applying a horizontal force $F$ but the body is not moving then

A bullet of mass $m$ moving with velocity $v$ strikes a block of mass $M$ at rest and gets embedded into it. The kinetic energy of the composite block will be
