145⁰ I I 2m, q E 5) A point charge with known mass 2m and unknown positive charge q is suspended on a massless string in a uniform horizontal field of known magnitude E. The string makes a stationary angle = 45° with the vertical. What is a correct expression for the charge q? (HINT: draw a free-body diagram.)
