  • B. 80J
  • C. 1500J
  • D. 20J
Correct Answer: Option A - Given, Force = 50N Displacement = 30m Work = force x displacement W = 50 x 30 = 1500J
A. Given, Force = 50N Displacement = 30m Work = force x displacement W = 50 x 30 = 1500J

Explanations:

Given, Force = 50N Displacement = 30m Work = force x displacement W = 50 x 30 = 1500J
