Consider the following image : A proton enters a magnetic field at right angles to it, as shown above. The direction of force acting on the proton will be

Options

  1. Ato the right
  2. Bto the left
  3. Cout of the page
  4. Dinto the page

Correct answer

D. into the page

Step-by-step solution

We know that both the directions are perpendicular, thus for force direction = ? Using Fleming's left hand rule, Direction of force is perpendicular to the direction of magnetic field and current. Thus direction of force is opposite to electron motion into the page at 90^ .
