Figure shows tracks of three charged particles in a uniform electrostatic field. Give the signs of the three charges. Which particle has the highest charge to mass ratio?:

Shows the tracks of three charged particles crossing a uniform electrostatic field with same velocities along horizontal. Give the signs of the three charges. Which particle has the highest charge to mass ratio?

The energy of a charged particle moving in a uniform magnetic field does not change. Why? Explain.

A charged particle is moving through magnetic field. Then, magneti field

A positively charged particle is released from rest in an uniform electric field . The electric potential energy of the charge:

A charged particle enters a uniform magnetic field experience an upward force as indicated in the figure. What is the charge sign on this particle?

When a charged particle moves perpendicular to a magnetic field, then

A charged particle enters at 30^@ to the magnetic field. Its path becomes.

Show that the frequency revolution of a charged pawrticle in a uniform magnetic field vecB(vecB=Bhatk) , is independent of the speed. Which particle machine makes use of this fact? What is the frequency of the alternating electric field, used in this machine?
