JEE MAIN - Physics (2005 - No. 12)
A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected along the direction of the fields with a certain velocity then
its velocity will increase
Its velocity will decrease
it will turn towards left of a direction of motion
it will turn towards right of direction of motion
Paliwanag
Due to electric field, it experiences force and decelerates i.e. its velocity decreases.
