The diagram shows the electric field lines between two electrical charges P and Q. Which of the following statements about the charges on P and Q is correct?

a. P is positive and Q is negative

b. P is negative and Q is positive

c. P and Q are both positive

d. The charge cannot be determined with only field lines

A

Explanation:

The P is +ve because as you can see the arrows around it are going out. That is what makes P +ve and Q is -ve for the same reason. The arrows are going to it

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.

inverse v=i*r
