Statements I: Kinetic energy of ‘A’ on sliding to J will be greater than the kinetic energy of B on falling vertically to M. Statements II: Acceleration of ‘A’ will be greater than acceleration of ‘B’ when both are released to slide on inclined planes.
Statements III: Work done by external agent to move block slowly from position B to O is negative

  1. Statement I is true    
  2. Statement II is true    
  3. Statement III is true

The sphere at P is given a downward velocity v0 and swings in a vertical plane at the end of a rope of l = 1 m attached to a support at O. The rope breaks at angle 30° from horizontal, knowing that it can withstand a maximum tension equal to three times the weight of the sphere. Then the value of v0 will be: open parentheses g equals fraction numerator pi to the power of 2 end exponent m over denominator s to the power of 2 end exponent end fraction close parentheses
