A mass M collides elastically with a stationary mass m. If M < m, then it is possible for M to bounce directly backwards. However, if M > m, then there is a maximum angle of deflection of M. Then angle is

- a)sin φ = M/m
- b)sin φ = m/M
- c)tan φ = M/m
- d)tan φ = m/M

Correct answer is option 'B'. Can you explain this answer?

Consider a uniform spherical charge distribution of radius R_{1} centred at the origin O. In this distribution, a spherical cavity of radius R_{2}, centred at P with distance OP = a = R_{1} – R_{2} (see figure) is made. If the electric field inside the cavity at position then the correct statement(s) is (are)

Answer the following by appropriately matching the lists based on the information given in the paragraph.

In a thermodynamic process on an ideal monatomic gas, the infinitesimal heat absorbed by the gas is given by TΔX, where T is temperature of the system and ΔX is the infinitesimal change in a thermodynamic quantity X of the system. For a mole of monatomic ideal gas Here, R is gas constant, V is volume of gas, T_{A} and V_{A} are constants.

The List-I below gives some quantities involved in a process and List-II gives some possible values of these quantities.

If the process carried out on one mole of monatomic ideal gas is as shown in figure in the PV-diagram with the correct match is,
