Less than 50 N.
Work Step by Step
The diagonal of a parallelogram represents the resultant, or sum, of the two vectors that are used to construct the parallelogram. This is discussed on page 29. Draw a parallelogram representing the 2 rope forces, where the upward resultant force is equal and opposite to the lantern’s weight. Your diagram in this case will show that the tension in each rope is less than 50 N.
