Which best describes the electric field created by a positive charge? it circles clockwise around the charge. it circles counterclockwise around the charge. its rays point away from the charge. its rays point toward the charge.

Its rays point away from the charge.

Explanation:

The electric field due to a point charge is given by :

Where

k is the electrostatic constant

q is the point charge

r is the distance from charge particle

It is clear that the electric field is directly proportional to the charge and inversely proportional to the distance from charge particle.

There are two types of charged particle i.e. negative and positive charge. For a positive charge, the direction of electric field points away from it and for a negative charge, the direction of electric field points towards it.

Hence, the correct option is (c).

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
