Q: If someone travels 15 km distance with a fixed force of 500N, then calculate the work done.
  • A. 750000J
  • B. 75000J
  • C. 7500000J
  • D. 7500J
Correct Answer: Option C - Force = 500N , Work = ? Displacement = 15km = 15000m Work = force x displacement W = 500 x 15000 = 7500000J
C. Force = 500N , Work = ? Displacement = 15km = 15000m Work = force x displacement W = 500 x 15000 = 7500000J

Explanations:

Force = 500N , Work = ? Displacement = 15km = 15000m Work = force x displacement W = 500 x 15000 = 7500000J
