A rocket is fired upward from the earth surface such that it creates an acceleration of $19.6\, m / s ^{2}$. If after $5\, s$, its engine is switched off, the maximum height of the rocket from earth's surface would be
A $60\, kg$ weight is dragged on a horizontal surface by a rope through a distance of $2m$. If coefficient of friction is $ \mu =0.5, $ the angle of rope with surface is $60^{\circ}$ and $g=9.8\,m/{s}^{2}, $ then work done is
A 0.2 kg object at rest is subjected to a force $\left(0.3\hat{i}-0.4\hat{ j}\right)$ N. What is the velocity after 6 s?
As shown in the figure a magnet is moved with a fast speed towards a coil at rest. Due to this induced emf, induced current and induced charge in the coil is $E,\, I$ and $Q$ respectively. If the speed of the magnet is doubled, the incorrect statement is
