An object of mass 2 kilograms is moving along a circular path of radius 4 meters with a uniform speed of 6 meters per second. What is the magnitude of the centripetal force acting on the object?

💡 Solution & Explanation

The centripetal force required to keep an object moving in a circular path is calculated using the formula mass multiplied by the square of speed divided by the radius. Substituting the given values of mass equal to 2 kilograms, speed equal to 6 meters per second, and radius equal to 4 meters results in a force of 18 newtons. Incorrect choices arise from multiplying incorrectly or omitting the squaring of velocity. Centripetal force always acts toward the center of the circular trajectory.
