(A) If $c$ is the velocity of light

so, $E = h ν$ (Energy of photon)

(B) Velocity of photon is equal to velocity of light i.e. c.

$p = \frac{h}{λ}$

$p = \frac{h v}{c}$

(D) In photon-electron collision both total energy and total momentum are conserved.

Direction for question 5 to 8: Go through the data set given below and solve the questions based on it.

If the rate of deceleration of the 8^th hour had continued further, the speed would have become zero in

Deceleration in 8^th hour = 20 km/h²

Speed at the end of 8^th hour = 50 km/h

Speed will be zero after 't' h where 0 = 50 – 20 * t

$= t = \frac{50}{20} = \frac{5}{2} h o u r s = 2 \frac{1}{2} h o u r s$

= speed will be zero at 10 h 30 minutes.
