Moving Charges ...

An electron is projected in the same direction of uniform magnetic field. Then

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

A proton and an electron enter a region with equal speed in which a magnetic field is suddenly switched on. The force experienced by them are

When a charged particle moves in a uniform magnetic field

A proton enters a magnetic field with a velocity of $$2.5\times 10^{7}ms^{-1}$$ making an angle $$30^{0}$$ with the magnetic field. The force on the proton is $$(B=25T)$$

A particle of mass $$M$$ and charge $$Q$$ moving with velocity $$\vec{v}$$ describes a circular path of radius $$R$$ when subjected to a uniform transverse magnetic field of induction $$\vec{B}$$. The work done by the field when the particle completes one full circle is 

A proton is rotating along a circular path with kinetic energy K in a uniform magnetic field B.If the magnetic field is made four times, the kinetic energy of rotation of proton is

A charged particle is moving with velocity $$v$$ in a magnetic field of induction $$B$$. The force on the particle will be maximum when

A particle of mass $$0.6$$ $$g$$ and having a charge of $$25$$ $$nC$$ is moving horizontally with a uniform velocity $$1.2 \times10^{4}$$ $$m/s$$ in a uniform magnetic field, then the value of the magnetic induction is (Take $$g=10 \ m/s^2$$)

A particle consisting of two electrons is moving in a magnetic field of $$(3i+2j) T$$ with a velocity $$5 \times 10^{5}\hat{i}m/s$$. The magnetic force acting on the particle will be
