A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected in the region such that its velocity is pointed along the direction of fields, then the electron

Options

  1. Aspeed will decrease
  2. Bspeed will increase
  3. Cwill turn towards left of direction of motion
  4. Dwill turn towards right of direction a motion

Correct answer

A. speed will decrease

Step-by-step solution

Field BB not applied only force. Field EE will apply a force opposite to velocity of the electron hence, speed will decreases.
