Question

Point a is 26 cm north of a point charge, and point b is 36 cm west of the charge. Determine (a) and (b)
(magnitude and direction).

Answer 1

Answer:

Electric Field and Electric Potential

An electric field at any point is equal to electric force per unit charge, experienced by an infinitesimally small test charge. It is a vector quantity. The formula for electric field is

E

=

k

q

r

Electric potential at a point is defined as the amount of work done to bring a unit positive charge from infinity to that point. Electric potential is a scalar quantity.

The formula for potential at a point is

V

=

k

q

r
