Question 6 1 pts A particle with electric charge -2 nC is located a distance of 1 cm from another particle with charge +4 nC resulting in a potential energy of -7.2 micro J. Another set of two particles has charges of +4 nC and -8 nC separated by 2 cm. What is the potential energy of this other system? +3.6 micro -7.2 micro ) 0 +7.2 micro +28.8 micro J - 14.4 micro Question 7 1 pts A1 kg block is pushed with constant force along a horizontal, frictionless track for a distance of 10 m. During this period the block accelerates from 2 m/s to 5 m/s. What is the magnitude of the constant force? 2.3 N 0 12.5 N 1.05 N 3N 0 1.25 N
