(a) Three pointcharges, A = 1.70 µC, B = 7.05 µC,and C = −4.40 µC, are located at thecorners of an equilateral triangle as in the figure above. Find themagnitude and direction of the electric field at the position ofthe 1.70 µC charge.
(b) How would the electric field at that point be affected if thecharge there were doubled?
--> The magnitude of the field would be halved.
-->The field would be unchanged.
-->The magnitude of the field would double.
-->The magnitude of the field would quadruple.
Would the magnitude of the electric force be affected?
Yes/No ?
