Question

Two charged particles of equal magnitude
(+Q and +Q) are fixed at opposite corners of a square that lies in a plane (see figure below). A test charge −q is placed at a third corner. If F is the magnitude of the force on the test charge due to only one of the other charges,what is the magnitude of the net force acting on the test charge due to both of these
charges?
1. Fnet = 2F/√3
2. Fnet = √2F
3. Fnet = 2F/3
4. Fnet = F
5. Fnet = 2F
6. Fnet = F/√3
7. Fnet = F/√2
8. Fnet = 3F/2
9. Fnet = 3F
10. Fnet = 0

Answer 1

What do you think? Two vectors F pointed in directions 90 degrees apart have what resultant? Think of the Pythagorean theorem. Draw a picture if necessary.

Answer 2

I thought it was 8 but im wrong

Answer 3

The answer is 2 that is correct
