Question

Statement 1: Specific charge of $\alpha$-particles is twice to that of proton.
Statement 2: Specific charge is given by e/m.

• A. If both Statement $1$ and Statement $2$ are true and the Statement $2$ is the correct explanation of the Statement $1$.
• B. If both Statement $1$ and Statement $2$ are true but statement $2$ is not the correct explanation of the statement $1$.
• C. If Statement $1$ is true but Statement $2$ is false.
• D. If Statement $1$ is false but Statement $2$ is true

Answer 1

Answer: (D)

Specific charge for proton =$\frac{e}{m}$ and specific charge of $\alpha=\frac{2e}{4m}=\frac{e}{2m}$
