The electric field at qa due to qb is:
Eab = 2.204 × 106 N/C
The electric field at qa due to qc is:
Eac = 9.80 × 105 N/C
In the figure, the point charges are located at the corners of an equilateral triangle 21 cm on a side.
Part (a) Find the magnitude of the electric field in N/C at the location of qa given that qb=10.8 uC and qc=4.8 uC.
Part (b) Find the direction of the electric field at qa, in degrees above the negative x-axis with origin at qa
Part (c) What is the magnitude of the force in N on qa given that qa=1.9 nC?
Part (d) What is the direction of the force on qa, in degrees above the negative x-axis with origin at qa?
