Homework Statement
I have a charge Q of +1.5*10^-7C located at co-ordinates (x,Y) (-6cm,0cm)
what is the force due to Q on a test charge of +1 C at the origin. Expressed as a vector.
The Attempt at a Solution
F= [tex]\frac{\kappa*Q1*Q2}{r^2}[/tex]
F= [tex]\frac{8.99*10^{9}*1.5*10^{-7}*1}{.06^{2}}[/tex]
F= 3.746*10 [tex]^{5}[/tex] N repulsive force.
How do I express this in [tex]\widehat{i}[/tex], [tex]\widehat{j}[/tex] unit vector notation?
