Zlatina is using a rope and pulley to suspend a mass of 15 kg. She uses a scale to measure the tension in the rope as she changes the angle at which she pulls, while always keeping the 15 kg mass at exactly the same spot Compare the tension in the rope when it makes an angle of 30° with respect to the vertical with the tension in the rope when it makes an angle of 60° with respect to the vertical. Her friend, Zora, now takes an identical mass and attaches hers directly to the ceiling with just a rope. She attaches a second rope to the mass and pulls it until the first rope makes an angle of = 20° with respect to the vertical, always keeping the second rope horizontal and the mass stationary. Find the tension in each rope.
