A charge of 3.0 nC is placed on the y axis at y = 3.0 cm and a 4.0 nC charge is placed on the x axis at x = 4.0 cm. If both charges are held fixed, what is the magnitude of the initial acceleration of a proton which is released from rest at the origin? The mass of proton is 1.67x10-27 kg OA 3.6x10¹2m/s² 08 4.2x10¹2m/s² oc 7.8x10¹2m/s² OD 1x10¹2m/s² OE 9x10¹2m/s²
