Charges q and q are placed on the x axis at x 0 and x 2.0, Ask an Expert

Academics

Q. Charges q and Q are placed on the x axis at x = 0 and x = 2.0 m, respectively. If q = -40 pC and Q = +30 pC, determine the net flux through a spherical surface (radius = 1.0 m) centered on the origin.

Q. The light ray makes an angle of α = 18.1° with the normal line at the boundary of linseed oil and water. Determine the angles θ1 and θ2. Note that n = 1.48 for linseed oil.
