Two charges +2 C and +17 PC are placed along the x axis, with the first charge at the origin (x = 0) and the second charge at < = +1 m. Find the magnitude and direction of the net force on a -2 nc
charge when placed at the following locations below.
Overall Hint
Review Section 5.3 Coulomb's Law . Use Coulomb's Law to calculate force due to each of two charges
and add them together for the net force, minding the directions. For part (c), you will need to do the
vector sum (more below).
la
a. halfway between the two charges: magnitude of force is 1.08
omn, and
the direction is in +x direction
b. on the x axis at 2 = -0.5 m: magnitude of force is 0.28
mN, and
the direction is in +x direction
c. at the coordinate (x, y) = (1 m, 0.5 m) (half a meter above the +17 PC charge in a direction
perpendicular to the line joining the two fixed charges):
Hint for (C)
This problem is fully 2-dimensional. The charge at x = 1 mexerts force along y direction; the
charge at the origin exerts force along the line connecting (x, y) = (0,0) and
(1, y) = (1 m, 0.5 m). Express each force vector in terms of u and y components; add the
components together, and calculate the magnitude of the resultant using Pythagorean theorem
Fy
and use tan(0) = to find the direction (draw the force diagrams to make sure your
F.
direction makes sense).
ut
Magnitude of force is 1.23
Omn, and the direction is
88.8
o degrees below - 3 axis.

Please help does anyone knows how to formula and please show all work
