If an object satisfies the first condition of equilibrium, then the rightward and leftward forces will be

Correct answer: A. Equal in magnitude but opposite in direction

  • A. Equal in magnitude but opposite in direction
  • B. Unequal in magnitude
  • C. Only rightward forces exist
  • D. Only leftward forces exist

Explanation

The first condition of equilibrium, also known as translational equilibrium, states that the sum of all forces acting on an object must be zero for it to be in equilibrium. This implies that all forces acting in the horizontal direction (rightward and leftward) must be equal in magnitude and opposite in direction. Therefore, the correct option is that the rightward and leftward forces are equal in magnitude but opposite in direction. The other options are incorrect because they do not satisfy this condition of equilibrium.

About Addition of Vectors

Vector addition combines directed quantities using the head-to-tail, parallelogram and component methods. Work includes finding the resultant magnitude and direction for two or more vectors, resolving vectors into perpendicular components, and distinguishing vector addition from scalar addition, where direction has no role.
