A 10-kg object hangs stationary from a rope attached to the ceiling. What is the tension in the rope? Use g = 9.8 m/s².
Explanation
📌 For a stationary object hanging vertically, tension must equal weight: T = mg = 10 × 9.8 = 98 N. Distractor A confuses mass (kg) with force (N); B uses g alone without multiplying by mass; D forgets that gravity is acting even on a stationary object.
