Question

# Assertion :$$\alpha$$ and $$\beta$$- particles suffer equal and opposite deflections in an external electric field. Reason: The specific charge of beta particles is larger than the specific charge of $$\alpha$$- particles

A
Statement I is True and Statement 2 is True and is a correct explanation of Statement 1.
B
Statement I is True and Statement 2 is True but not a correct explanation of Statement 1.
C
Statement I is True and Statement 2 is False
D
Statement I is False and Statement 2 is True.

Solution

## The correct option is D Statement I is False and Statement 2 is True.In an external field, Both experiences different amount of forces, $$\alpha$$ particle experiences twice the force but the mass of $$\alpha$$ particles are huge as compared to $$\beta$$ particles which are nothing but electrons. so, both experiences different deflections.For case of specific charge, in $$\alpha$$ particles the q/m ratio is very low as compared to $$\alpha$$ particles while charge on $$\alpha$$ particle is just twice that on $$\beta$$ particle.
