Question 1 of 12 > - /8.33 ... View Policies Current Attempt in Progress In the figure four particles form a square with edge length a = 2.11 x 10-2 m. The charges are q1 = q4 = 2.91 x 10-15 C and q2 = q3 = q. (a) What is q if the net electrostatic force on particle 1 is zero? (b) Is there any value of q that makes the net electrostatic force on each of the four particles zero? X 3 a) Number Units b)Question 2 of 12 > - /8.33 View Policies Current Attempt in Progress The magnitude of the electrostatic force between two identical ions that are separated by a distance of 8.00 x 10-10 m is 416.8 x 10-9 N. (a) What is the charge of each ion? (b) How many electrons are "missing" from each ion (thus giving the ion its charge imbalance)? (a) Number Units (b) Number Units v
