Which of the fractions given below is not equal to 15/23 ?
A uniform electric field and 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
v and B are in same direction so magnetic force on electron become zero, only electric force acts. But force on electron due to electric field is opposite to the direction of velocity
