CUET UG 2022 Physics Question Paper (18-Aug-2022) (Shift 2)

Question 1

An infinitly long wire is charged uniformly with charge density &lambda; and placed in air, the electric field at distance r from wire will be:

Accepted Answer

$\frac{\lambda}{2\pi \varepsilon_0r} $

Answer

$\frac{1}{4\pi \varepsilon_0} \frac{\lambda}{r}$

Answer

$\frac{1}{4\pi \varepsilon_0} \frac{\lambda}{r^2}$

Answer

$\frac{\lambda}{2 \varepsilon_0} $

Question 2

Two point charges (-q) and (+4q) are placed at separation 'r'. Where should a third charge be placed so that entire system of charges becomes in equilibrium?

Accepted Answer

at separation 'r' from (-q) on the extreme side of -q.

Answer

at separation 'r' from (4q) on the extreme side of 4q.

Answer

at separation $\frac{r}{2}$ from (-q) in between the two charges.

Answer

at separation $\frac{r}{4}$  from (4q) in between the two charges.
