If a charged particle kept at rest experiences an electromagnetic force,

If a charged particle at rest experiences no electromagnetic force, then The electric field must be zero

If a chraged particle at rest experiences no electromagnetic force, (i) the electric field must be zero (ii) the magnetic field must be zero (iii) the electric field may or may not be zero (iv) the magnetic field may or may not be zero

A He^(2+) at rest experiences an electromagnetic force. Then (where E is electric field and is B magnetic field)

The motion of a charged particle can be used to distinguish between a magnetic field and electric field in a certain region by firing the charge

A charged particle experience magnetic force in the presence of magnetic field. Which of the following statement is correct?

A charged particle is at rest in the region where magnetic field and electric field are parallel. The particle will move in a

A charged particle moving in a magnetic field experiences a resultant force

A charge particle is projected in a region of magnetic field and electric field if mass if mass of charged particle is m a its speed charges from V_(0) to 2V_(0) [W_(E)= work done by electric field W_(B)= work done by magnetic field] which statement is incorrect.?

Assertion If the path of a charged particle in a region of uniform electric and magnetic field is not a circle, then its kinetic energy may remain constant. Reason In a combined electric and magnetic field region a moving charge experiences a net force F=qE+q(VxxB), where symbols have their usual meanings.
