Hai noldong Two spiders are at rest next to one another, hanging from threads as in the picture. Both are charged with a value Q. Ignore the earth's electric field, the spiders will experience gravity (with acceleration g) and the electric field of the other spider. You know the mass of the spider, m, the angle each string makes relative to vertical, Theta, and the length of the string, L. 3. a. b. C. d. Draw the free body diagram of one spider. Write an expression for the tension that does not involve the charge. Write an expression for the charge that does not involve the tension. Sdr 2013
