Question

Two particles of equal charges after being accelerated through the same potential difference enter in a uniform transverse magnetic field and describe circular paths of radii $\mathrm { R } _ { 1 }$and .Then the ratio of their respective masses is

• A.
• B.
• C. $\left( \mathrm { R } _ { 2 } / \mathrm { R } _ { 1 } \right)$
• D.

Answer 1

Answer: (B)

Answer 2

And

Or

Or $M = \frac { B ^ { 2 } q ^ { 2 } R ^ { 2 } } { 2 q V } = \frac { B ^ { 2 } q R ^ { 2 } } { 2 V }$

(B, q, and V are same for the given two particles )

Hence
