hey!

the force exerted on a moving charge object is zero.

If you are asking about magnetic force on a moving charge in magnetic field, then it is stated by right hand rule which is that the force is perpandicular to the velocity of charge and the magnetic field direction. It is the vector product of velocity and magnetic field.

F = qvB sin theta

And it is ,

F = qvB  ; if theta = 90 degree as sin 90 = 1

where F is force on charge

q is magnitude of force

v is velocity of charged particle

B is magnetic field

theta is angle between v and B.

Hope it helps, Thankyou!
