Q1. A camping lamp is suspended by two unequal lengths of string attached to opposite points on a tent's frame. The longer string exerts a force (tension) of 9 N on the lamp while the shorter one exerts a force of 13 N. The longer string is inclined at 65 degrees to vertical, the shorter one at 39 degrees. Show that the horizontal resultant of these two forces on the lamp is zero. Work out the weight of the lamp.
