Assertion : An electron and a proton are...

Assertion : An electron and a proton are accelerated by same potential difference and then enter in uniform transverse magnetic field. The radii of the two will be different.
Reason : Charges on them are different.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`:'r=((2qVm))/(Bq)impliesrpropsqrt(m/q)`
`m and q both are different. Ratio `m/q` is not same for both.
