List of top Physics Questions on Electric field and potential due to point asked in CUET (UG)

The Young's double slit interference experiment is performed using light consisting of \(480\ \text{nm}\) and \(600\ \text{nm}\) wavelengths to form interference patterns. The least number of the bright fringes of \(480\ \text{nm}\) light that are required for the first coincidence with the bright fringes formed by \(600\ \text{nm}\) light is:

Two-point charges, $q_1 = 36\ \mu\text{C}$ and $q_2 = -9\ \mu\text{C}$ are placed at a distance of $30\text{ cm}$. What distance from $q_1$, where the net electric field is zero, will be:

A conducting sphere of radius R is given a charge Q. What is the electric field and the electric potential at the centre of the sphere?

A \(ẞ\)-particle is moving perpendicular to the uniform electric field created by a potential difference of \(6 × 10^3\) V across parallel metal plates separated by a vertical distance of 6 cm. What is the acceleration of the beta particle between the plates? (Mass of electron = \(9.1 × 10^{-31}\)kg)
