Three positive particles of equal charge,+11.0uc, are located at the corners of an equilateral triangle of side 15,0cm calculate the magnitude and direction of the net force on each particle.
Here is what I got so far f1= kq1q2/r^2 =(9.0*10^9N*m^2/c^2/)(11.0*10^-6)^2= 48.4N
F1 = COS30(48.4)= 41.9N
SIN30(48.4) =24.2N
I tried to find the square root of 41.9^2+24.2^2 and I didn't get my didn't my desired answer. How would I find the direction of each particle?
This one I have no idea on how to solve.Two small nonconducting spheres have a total charge of 90.0uc. (a) when placed 1.06m apart, the force each exerts on the other is 12N and is repulsive. What is the charge on each? (b) what if the force were attractive?
Here is another one
Two point charges have a total charge of 560uc. When placed 1.10m apart, the force exerts on the other is 22.8N and is replsive. What is the charge on each?
What is the best way to solve all Coulomb's law Problems? Thanks in advance for your help.
