Question

if a 10kg object is suspended by a rope, what is the tension in the rope? a. 100n b. 98n c. 10n d. 80n

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
