Hint: Surround the charge Q by a hypothetical spherical surface of radius r and find the product of the electric field due to Q and the surface area of the sphere. 12. Charge Q is distributed uniformly throughout a sphere of radius R (Fig. 6 below).
Dec 02, 2015 · Ans.Let us consider charge +q is uniformly distributed over a spherical shell of radius R. Let £ is to be obtained at P lying outside of spherical shell. Eat any point is radially outward (if charge q is positive) and has same magnitude at all points which lie at the same distance r from centre of spherical shell such that r> R. Ans.
• Considering the charge is uniformly distributed, the use of the charge density is convenient in calculating the over a line, surface or volume. • If charge is distributed uniformly throughout a volume V, the volume charge density ρ is defined as V Q Where ρ has units of coulombs per cubic meter (C.m-3)
Jan 09, 2018 · The smaller shell has charge q1 = +6.00 nC distributed uniformly over its surface, and the larger shell has charge q2 = -9.00 nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells.
Consider a spherical surface centered around the point charge q (see Figure 24.2). The direction of the electric field at any point on its surface is perpendicular to the surface and its magnitude is constant. This implies that the electric flux [Phi] through this surface is given by (24.3)
The inside of the conducting liquid is field-free. Electrons redistribute themselves, leaving the point charges shielded by excess positive charges. The excess negative charge distributes itself uniformly over the outer surface of the conducting fluid. Details of the calculation: Put the origin of the coordinate system at the center of the ball.
A charge Q is distributed uniformly over the surface of a spherical shell of radius R. How much work is required to move these charges to a shell with half the radius? The charges are uniformly distributed. Solution. The potential energy of charge q on a sphere is kq/R, where R is the radius of the sphere. The energy to add a small increment of ...
