6 Electric forces and charge magnitude Two charged particles, A on the left and B on the right, are held at fixed locations. The charges on the particle can be adjusted while their locations stay fixed. a) Suppose that the charge of B is tripled. By how many times does this increase the fore that A exerts on B? Explain your answer. b) Suppose that the charge of B is tripled. By how many times does this increase the force...

HOMEWORK FOR LAB 1 ELECTRIC CHARGES, FORCES AND FIELDS 1. You have two charged pieces of Scotch Magic tape. How would you deter- mine if they have like or unlike charges? What would you need to determine if they are charged positively or negatively? 2. Two like charges are separated by some distance. Describe quantitatively what will happen to the force exerted by one charge on the other if The distance between the charges is doubled a· b. The distance...

19 Electric field produced by two point charges Two charged particles are held fixed as illustrated; the grid units are each 0.010m. The aim of this exercise will be to determine the field at point P a) Indicate the directions of the electric fields produced by each source charge at point P 2.0nC b) Determine the magnitude of the electric field produced -40nC by each source charge at point P. c) Using vector components add the two electric fields.
