PHYSICS 6B Ch.17 Worksheet www.clas.ucsb.edu/staff/vince/ 1) Find the magnitude of the electric force between two 1.00-C charges separated by 1.00m. N 10 9 ) m 1 ( ) C 1 )( C 1 )( 10 9 ( R Q kQ F 9 2 C m N 9 2 2 1 elec 2 2 2) A charge q 1 = -5.4 μC is at the origin, and a charge q 2 = -2.2 μC is on the x axis at x=1.00. Find the net force acting on a charge q 3 = 1.6 μC located at x = 0.75m 3) An electron and a proton, initially separated by a distance d, are released from rest simultaneously. The two particles are free to move. When they collide, are they (a) at the midpoint of their initial separation, (b) closer to the initial position of the proton, or (c) closer to the initial position of the electron? Answer (b) – the forces are equal magnitude, so the acceleration of the proton is much slower due its larger mass. So the electron moves much faster, putting the collision nearer to the proton’s initial position. 4)
