1. Two point charges,
equal amounts of charge in absolute value 2,5 C and opposite in sign, are in the air at a distance of 10 cm from each other. How big is it the intensity of the electrostatic force with which these two point charges act on each other? Comment on the sign of force.
Mike walks 100 meter north, then walks 30 meters south. after this, he walks another 10 meters north. what is the magnitude of his total displacement during this walk,in meters?
What is the electric force acting between two charges of -0.0045 c and -0.0025 c that are 0.0060 m apart? use fe=kq1q2/r^2 and k = 9.00 x 10^9 n*m^2/c^2 a. 1.7 x 10^7 n b. -1.7 x 10^7 n c. -2.8 x 10^9 n d. 2.8 x 10^9 n
