Consider the following in respect of moment of a force: 1. The moment of force about a point is independent of point of application of force. 2. The moment of a force about a line is a vector quantity. Which of the statements given above is/are correct?

  • A
    1 only
  • Correct answer
    B
    2 only
  • C
    Both 1 and 2
  • D
    Neither 1 nor 2
