In the above diagram, two charged particles A
, which are entered into a uniform electric field with the same velocity, move along their respective curved paths. The resulting horizontal movements of A
in the electric field are \(2d\) and \(3d,\) respectively. Let \(W_A\) and \(W_B\) be the works done by the electric field to the charged particles A
, respectively. What is the ratio \(W_A:W_B\)?
Ignore the gravitational force.
