WebA charged sphere of radius 2a and original volume charge density p =+4 mng'm3 has a small sphere removed from it. Find the magnitude of electric potential at point P (03!). ... Potential due to large sphere- potential due to removed sphere = kρ[V1/.008-V2/.005] where V= sphere volume. k*ρ*4/3π[(2a)^3/.008- a^3/.005] on plugin all values ... The electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field. More precisely, it is the energy per unit charge for a test charge that is so small that the disturbance of the field under consideration is negligible. Furthermore, the motion across the field is supposed to proceed with negligible accel… broach sharpening services

WebTo calculate the electrostatic interaction between a charged sphere and a charged surface under the condition of constant charge density on the two surfaces is difficult. The theory presented in this paper provides an approximate solution to this problem when the charge of the two bodies is of opposite sign. The proposed calculation model is ... WebA sphere of radius 75 cm is charged to a potential of 1.5 MV. Following the electrical discharge, the sphere loses 95% of its energy. Calculate: a) The capacitance of the sphere. b) The potential of the sphere after discharging. Part (a) Step 1: List the known quantities Radius of sphere, R = 75 cm = 75 × 10 −2 m Webimage charge inside the sphere), then the potential on the sphere is still zero. This is most easily seen if we write the potential due to the two point charges in spherical coordinates. At a location r the potential due to the original charge is V q= 1 4ˇ 0 q p r 2+a 2arcos (1) where we’ve used the cosine rule to get the distance from qto ... broach something
