Statement : Specific charge of alpha-pa...

Statement : Specific charge of ` alpha`-particles is twice to that of proton .
Explanation : Specific charge is given by `e//m`

A

S is correct but E is wrong

B

S is wrong but E is correct.

C

Both S and E are correct and E is correct explanation of S

D

Both S and E are correct but E is not correct explanation of S

Text Solution

Verified by Experts

The correct Answer is:
B
Specific Charge for proton =e/m and specific charge of `alpha=(2e)/(4m) =e/(2m)`
