For the net force on the ring to equal zero, we must have = 1 2 3 = 0. Rearranging, we find that 3 = ( 1 2) In other words, for the 3rd force to balance the first two, 3 must be equal in magnitude and opposite in direction to 1 2. Using your values for the magnitudes and directions of 1 2 in Calculation Table 2, determine the theoretical magnitudes and directions for 3. Enter these values in the 3, (N) and 3, columns in Calculation Table 3
