AIEEE 2013 PYQ Mock Test

Statement- I: Higher the range, greater is the resistance of ammeter.Statement- II: To increase the range of ammeter, additional shunt needs to be used across it.

What is the minimum energy required to launch a satellite of mass $m$ from the surface of a planet of mass $M$ and radius $R$ in a circular orbit at an altitude of $2R$?

A projectile is given an initial velocity of $(\hat{i}+2\hat{j})\text{m/s}$, where $\hat{i}$ is along the ground and $\hat{j}$ is along the vertical. If $g=10{\text{m/s}}^2$, the equation of its trajectory is:

Two capacitors $C_1$ and $C_2$ are charged to $120\text{V}$ and $200\text{V}$ respectively. It is found that by connecting them together the potential on each one can be made zero. Then:

A hoop of radius $r$ and mass $m$ rotating with an angular velocity ${\omega }_0$ is placed on a rough horizontal surface. The initial velocity of the centre of the hoop is zero. What will be the velocity of the centre of the hoop when it ceases to slip?
