Two long, straight, parallel wires 24 cm apart carry currents of I1 = 30A and
I2 = 20A in the same direction. Determine the magnetic field in the plane of the two wires at a point halfway between the wires.

An electron and a proton, having the same kinetic energy, enter a region of uniform magnetic field moving perpendicular to the field. Calculate the ratio of the radii of their circular paths in the field.

The polarisability of a given material is 1.0×10^-40 C^2 mN^−1 . Determine its dielectric constant if the number of molecules in 1 m^3 volume of the material is 5.0×10^25.
