Assertion: if wavelength of light is doubled, energy and momentum of photons are reduced to half. Reason: By increasing the wavelength, speed of photons will decrease.

Assertion (A) : Rate of reaction will be doubled, when temperature increased from 298 k to 308 k. Reason (R ): The activation energy of reaction decreases with increase in temperature.

Assertion : When the speed of an electron increases its specific charge decreases. Reason : Specific charge is the ratio of the change to mass.

Assertion: The alternating current lags behined the e.m.f. by a phase angle of pi//2 , when AC flows through an inductor. Reason: The inductive reactance increases as the frequency of AC source decreases.

Assertion : When an automobile while going too fast around a curve overturns, its inner wheels leave the ground first. Reason : For a safe turn the velocity of automobile should be less than the value of safe limit velocity.
