The work done by a force when it acts over a distance and is separated by an angle can be calculated using the formula:
[ W = F cdot d cdot cos(theta) ]
where:
– ( W ) is the work done,
– ( F ) is the magnitude of the force,
– ( d ) is the distance moved in the direction of the force,
– ( theta ) is the angle between the force vector and the direction of motion.
Answer: b
Explanation: Force is a vector quantity, whereas distance is scalar. Work is defined as
the product of force and distance, which is given by dot product.
