A rod coincident with the z-axis extends from 0 to -L. If the rod carries a uniform charge density of pL (a) calculate the electric field intensity at a point h on the z-axis. (b) Use your answer to show that when h>>L the rod behaves as a point charge of value plL . (c) How much larger than the length of the rod must h be in order that the answer to part b) is a reasonably accurate estimate.
The separation of two point charges with charges Q1=36pC and ,Q2=9pC respectively, is 3 cm. If a third point charge Q3 is placed on the line joining Q1 and Q2 at a distance d from Q1 find Q3 and d that ensures that the force on all charges is zero.

- 5. The electric field on the positive z-axis due to a uniformly charged disk of radius a that lies in the x-y plane with center at the origin is claimed to be given by - Ps Z 2E 2 a² + z² Where ps is the surface charge density on the disk. Without deriving this formula, evaluate it for its probable correctness. (a) Is its symmetry correct? Explain. (b) If z>> a, it reduces to that of a point charge of value a²ps (c) if z> z is large the formula reduces to that of an infinite plane.arrow_forwardทำโจทย์arrow_forwardA rod coincident with the z-axis extends from 0 to L.
