A7.45 nc charge is located 1.66 m from a 4.22 nc point charge. (a) find the magnitude of the electrostatic force that one charge exerts on the other.(b) is the force attractive or repulsive? i. attractiveii. repulsive

a.

b.Repulsive

Explanation:

We are given that

r=1.66m

We know that

Electrostatic force =

r=Distance between

k=Constant=

Using the formula

a.The magnitude of the electrostatic force=

The magnitude of the electrostatic force=

b.Both charge are positive .We know that when like charges repel each other and unlike charges attract to each other.

Therefore, the force between given charges is repulsive.

find the sum of the two horizontal vectors and the sum of the two vertical vectors

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.
