Solution
The correct options are B Rate of change of speed of the electron is constant D The net force acting on electron is provided by electrostatic attraction
The net force acting on the electron required for circular motion of electron is provided by the elctrostatic attraction
Speed of the electron is constant hence the rate of change of speed is also constant and zero
At any instant the direction of acceleration of the electron is along the radial line, i.e. direction of radius is changing. Therefore rate of change of velocity is not constant for the given system.
