if a 10kg object is suspended by a rope, what is the tension in the rope? a. 100n b. 98n c. 10n d. 80n
Answer
Explanation:
Step1: Analyze the forces
When the object is suspended and in equilibrium, the tension (T) in the rope balances the weight (W) of the object.
Step2: Calculate the weight
The weight of an object is given by (W = mg), where (m = 10\space kg) and (g=9.8\space m/s^{2}). So (W=10\times9.8 = 98\space N). Since (T = W) (equilibrium condition), the tension (T = 98\space N).
Answer:
B. 98N
