Homework Statement
A rod 11.9 cm long is uniformly charged and
has a total charge of −17.7 μC.
Find the magnitude of the electric field
along the axis of the rod at a point 46.2418 cm
from the center of the rod. The Coulomb con-
stant is 8.98755 × 109 N · m2/C2.

so #3 is the same as #1?
i used the equation to calculate the e field for the 2 points: origin to the right of the origin, and origin to south of origin. then i took the square root of the squares of those values, and got part 1 again?
Homework Statement
Consider three charges in a triangle as shown.
1. What is the net electric force on the charge at the origin?
2. What is the direction of this force(between -180 and 180)?
3. What is the magnitude of the net electric field at the position of the charge at the...
What i don't understand is, my professor did a similar problem in class, except with 3 charges, and used the units in microcoloumbs and got the right answer? Or should i be doing all the problems in coloumbs instead?
Homework Statement
Part 1:
A charge of 2 µC is at the origin, and a charge
of 6 µC is on the x-axis at x = 1 m.
