In Thomson's experiment if the value of $q/m$ is the same for all positive ions striking the photographic plate, then the trace would be

A

Straight line

B

Parabolic

C

Circular

D

Elliptical

Solution

As we know,

$z ^2= k \left(\frac{ q }{ m }\right) y$

since $\frac{ q }{ m }$ is constant,

tracjectory equation is $X ^2= Y$

hence, a parabola.
