Question 7

A point charge with a charge of 5C is fixed at point (3m,0). A second point charge with a charge of -2 C is fixed at point (0,1m).

QUESTION 7.1

7A

• A)What is the electric field at the origin in unit vector notation?(E=####i+####j)

(Hint: be careful about the signs as they indicate direction)

QUESTION 7.2

7B

If a third point charge with charge of 9 C was placed at the origin, what would be the net force on the third charge by the other two in unit vector notation.

QUESTION 7.3

7C

If the third charge had a mass of 2kg and was free to move without friction, what would be its acceleration when first released in unit vector notation?
