Three charges are arranged as shown in figure below (a) Find the magnitude and direction of the electrostatic force on the charge at the origin. (b) Determine the electric filed and electric potential at a point P (-0.30 m, -0.10 m). (c) How much work is required to bring a point chare 2 nC from infinity to point P?​

the answer is a 3.8cm

explanation:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
