I need a little help with this problem.

A 2.20 10-9 C charge has coordinates x = 0, y = -2.00; a 2.70 10-9C charge has coordinates x = 3.00, y = 0; and a -5.05 10-9 C chargehas coordinates x = 3.00, y = 4.00, where all distances are in cm.Determine magnitude and direction for the electric field at theorigin and the instantaneous acceleration of a proton placed at theorigin.

A)Determine the magnitude and direction for the electric field atthe origin (measure the angle counterclockwise from the positivex-axis).
Magnitude:
Direction:

B) Determine the magnitude and direction for the instantaneousacceleration of a proton placed at the origin (measure the anglecounterclockwise from the positive x-axis).
Magnitude:
Direction:
