A charge of lies on an isolated metal sphere of radius 16.0 cm. With at infinity, what is the electric potential at points on the sphere’s surface?
The electric potential at points on the sphere’s surface is .
For the isolated metal sphere:
The value of the charge
Use the equation of the electric potential at points on the sphere’s surface.
The electric 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.
The electric potential is define by,
Here, V is electric potential, R is distance between the point charges, q is charge, is the permittivity of free space, and k is the Coulomb’s constant having a value .
The electric potential on the sphere is,
Substitute known values in the above equation.
Hence, the electric potential at points on the sphere’s surface is 844 V.
Question: A plastic disk of radius R = 64.0 cm is charged on one side with a uniform surface charge density , and then three quadrants of the disk are removed. The remaining quadrant is shown in Fig. 24-50.With V =0 at infinity, what is the potential due to the remaining quadrant at point P, which is on the central axis of the original disk at distance D = 25.9 cm from the original center?
Identical charges are fixed on an x axis at . A particle of charge is then released from rest at a point on the positive part of the y axis. Due to the symmetry of the situation, the particle moves along the y axis and has kinetic energy 1.2 J as it passes through the point . (a) What is the kinetic energy of the particle as it passes through the origin? (b) At what negative value of y will the particle momentarily stop?
