Statement: Rutherfored studied the firest nuclear reaction:
`._(7)^(14)N + ._(2)^(4)He rarr ._(8)^(17)O + ._(1)^(1)H + 1.193 MeV`
Explanation: `alpha-` particels lesser than energy `7.6 MeV` were found ineffective.

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:
`d`
`alpha-` particles with energy lesser than `7.6 MeV` were not capable to penerate nucleaus and over power the repusilve forces.
