Unformatted text preview: 3. Shown in the figure below are two point charges, Q1 and Q2 , and the location of point P . All locations (x,y) in the figure are labelled in meters. Evaluate all of the following: Point P (x=4, y=4) Q = +4 µ C (x=−1, y=0) Q = −2 µ C (x=2, y=−1) (a) Find the magnitude and direction of the electric field, E at the point P. (b) What would be the magnitude of the force on a particle of charge q = 4µC placed at point P. (c) What is the potential, V, at the point P? (d) How much work is required to bring the q = 4µC charge from infinity to the point P. (e) Assume that the q = 4µC charge has a mass of m = 12µg and is released from rest starting at the point P. What will be the velocity of this mass when it reaches infinity (note: non-relativistic)? 3 ...
