Question
A point charge with q1 = +2.7 C is located at x = 3.0 m, y = 0, and a second point charge with q2 = +6.4 C is at x = +1.0 m, y = +2.0 m (see figure below).
(a) What is the force exerted by q1 on q2?
(b) What is the force exerted by q2 on q1?
Both are in Newtons. I have the angles, but not the magnitudes.
Explanation / Answer
full problem is not given anyway i am finding electostatic force betweem two charges.......
F= K*q1*q2/r^2.....
F= 9*10^9*2.7*6.4/r^2....
here r is distance between two charges....= (1+3) i +(2-0) j.....=4 i +2 j.....=sqrt(16+4)= 4.472 m....
F= 9*10^9*2.7*6.4/r^2....=7.776*10^9 N
