In a conical pendulum, a bob of mass 'm' moves in a horizontal circle of radius 'r' with uniform speed 'V'. The string of length 'L' describes a cone of semi-vertical angle 'θ'. The centripetal force acting on the bob is given by (where g is the acceleration due to gravity):

Which of the following forces is/are responsible for the sedimentation of particles during centrifugation?

Which of the following forces always opposes the applied motion or force?

Statement: An object of mass M falls freely under gravity, maintaining a constant acceleration. Conclusion I: The velocity of the object increases uniformly with time. Conclusion II: The acceleration of the object depends on its mass. Choose the correct option:
