In the following diagram, which particle has highest (e / m ) value?

Options

  1. A(A )
  2. B(B )
  3. C(C )
  4. D(D )

Correct answer

D. (D )

Step-by-step solution

(e v B= m v^2 r ) ( e m 1 r ), if (B ) and (v ) are the same. The radius of curvature of (D ) is minimum. Therefore ( e m ) is maximum.
