Based on the above information, if another small charge experiences a force of 8.00 10-15 N, when placed at a point where the electric field is 2.50 10 N/C, then the small charge is most likely a/an: O a. electron O b. proton O c. hydrogen nucleus O d. alpha particle Two charges of -5.10 C and -2.50 C are placed 1.50 cm apart, as shown 1.50 cm -5.10 C 3.20 cm -2.50 C
