moving charged particles

(v x B) is normal to v and work done by it is zero. In a uniform magnetic field B, the charge q described in (7) executes circular orbit in the plane normal to B. Its frequency of uniform circular motion is called the cyclotron frequency and is given by: This frequency is independent of t..

2) When the charges move parallel or anti-parallel to the magnetic field, q = 0 o or 180 o , the is zero in such cases. ..

The proton is equal and opposite to the charge of an electron. So the absolute charge of a proton is 1.6 x 10 - 1 9 coulomb of positive charge. This being the smallest positive charge carried by any particle, it is taken as 1 unit positive ..

01. - A straight wire carrying a current of 12 A is bent into a semi-circular arc of radius 2.0 cm as shown in the figure. What is the direction and magnitude of at the centre of the arc? What would your answer change if the wire were bent into a semi-circular arc of the same radius but in the oppo..

03. - Two concentric circular coils X and Y of radii 16cm and 10cm respectively lie in the same vertical plane containing the north-south direction. Coil X has 20 turns and carries a current of 16 A; coil Y has 25 turns and carries a current of 18A. The direction of current in X is anticlockwise an..
