Question
A 1000 kg load is being moved by a crane. Find the tension in the cable that supports the load as it is accelerating upward at 2 ms⁻². (acceleration due to gravity, g = 10 ms⁻²)
Correct Answer
Option C is the correct answer.
Detailed Explanation
When accelerating upward, T - mg = ma. So T = m(g + a) = 1000(10 + 2) = 1000 × 12 = 12,000 N.
Hint
For upward acceleration, tension = m(g + a).
