A rectangular loop of area vector $\vec{A} = [\hat{i} + \sqrt{3}\,\hat{j}] \times 10^{-2}\,\text{m}^2$ is placed in a magnetic field $\vec{B} = [4.0t^2 + 2.0]\,\hat{i}$, where $B$ is in tesla and $t$ in seconds. At $t = 1.0$ s, the magnitude of induced emf in the loop is:

Two statements are given — one labelled as Assertion (A) and the other labelled as Reason (R). Select the correct answer from the options below:

(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
(D) Both Assertion (A) and Reason (R) are false.

Assertion (A): In process of photoelectric emission using a monochromatic light, all emitted electrons do not have the same kinetic energy.

Reason (R): If radiation falling on a photosensitive surface consists of different wavelengths, the energy of emitted photoelectrons by absorbing photons of different wavelengths, shall be different.

A galvanometer having a coil resistance of $48\,\Omega$ shows full-scale deflection for a current of $2.0$ A. It can be converted into an ammeter of range $(0-10\,\text{A})$ by connecting:

In a Rutherford scattering experiment, when an alpha particle of mass $m_1$ approaches a target nucleus of charge $Ze$ and mass $m_2$, the distance of the closest approach is $d_0$. The energy of the particle is:

Define the term, ‘distance of closest approach’. A proton of 3.95 MeV energy approaches a target nucleus $ Z = 79 $ in head-on position. Calculate its distance of closest approach.
