A conducting sphere of radius ' $\text{R}$ ' is given a charge ' $Q$ ' uniformly. The electric field and the electric potential at the centre of the sphere are respectively [ $\varepsilon_0 =$ permittivity of free space]}

In an isobaric process of an ideal gas, the ratio of heat supplied and work done by the system $\left(\frac{\text{Q}}{\text{W}}\right)$ is $\left[\frac{\text{C}_{\text{P}}}{\text{C}_{\text{V}}} = \gamma\right]$.

When cell of e.m.f. ' \( E_1 \) ' is connected to potentiometer wire, the balancing length is ' \( l_1 \) '. Another cell of e.m.f. ' \( E_2 \) ' (\( E_1>E_2 \)) is connected so that two cells oppose each other, the balancing length is ' \( l_2 \) '. The ratio \( E_1 : E_2 \) is

A hollow charged metal sphere has a radius ' \(r\) '. If the potential difference between its surface and a point at a distance ' \(3r\) ' from the centre is ' \(v\) ', then the electric field intensity at a distance ' \(3r\) ' is
