A magnetic field $$4\times 10^{-3}\hat{k}T$$ exerts a force $$(4\hat{i}+3\hat{j})\times 10^{-10}N$$ on a particle having a charge $$10^{-9}$$C and going in the X-Y plane. The velocity of the particle is

A charged particle is projected in a magnetic field $$\vec{B}=(3\vec{i}+4\vec{j})\times 10^{-2}T$$ and the acceleration is found to be $$\vec{a}=(x\vec{i}+2\vec{j})m/s^{2}$$. The value of x is :

Assertion: If an electron is not deflected while passing through a certain region of space, then only possibility is that there is no magnetic field in this region

A charge having q/m equal to $$10^8$$c/kg and with velocity 3 x$${ 10 }^{ 5 }$$   m/s enters into a uniform magnetic field B = 0.3 tesla at an angle 30 with direction of field. Then radius of curvature will be : 

Which of the following statement is not correct about two parallel conductors carrying equal currents in the same direction?

How will two parallel beams of electron behave while moving in the same direction?

A tesla is equivalent to a

A positively-charged particle (alpha-particle) projected towards west is deflected towards north by a magnetic field. The direction of magnetic field is in which direction?

A uniform magnetic field exists in the plane of paper pointing from left to right as shown in Figure. In the field an electron and a proton move as shown. In what direction the electron and the proton experience force ?

An electron and a proton move in a uniform magnetic field with same speed $$20 \ m/s$$ perpendicular to the magnetic field ($$1 T$$). What are the forces they will experience ?
