# repels

Verb

- third-person singular simple present indicative form of repel

- He also discovered that a body charged with positive or negative electricity
**repels**a body free to move when the latter is charged with electricity of like sign, but attracts it if it is charged with electricity of opposite sign, i.e. - Positive
**repels**positive and negative**repels**negative, but positive attracts negative. - A very small sphere is said then to possess a charge of one electrostatic unit of quantity, when it
**repels**another similar and similarly electrified body with a force of one dyne, the centres being at a distance of one centimetre, provided that the spheres are in vacuo or immersed in some insulator, the dielectric constant of which is' taken as unity. - The explanation is as follows: the charge (-}- Q) of positive electricity on the ball creates by induction an equal charge (- Q) on the inside of the canister when placed in it, and
**repels**to the exterior surface of the canister an equal charge (+ Q). - Having a charge Q
**repels**a unit charge placed at a distance x from its centre with a force Q/x 2 dynes, and therefore the work W in ergs expended in bringing the unit up to that point from an infinite distance is given by the integral W = Q x 2 dx = Hence the potential at the surface of the sphere, and therefore the potential of the sphere, is Q/R, where R is the radius of the sphere in centimetres.
