TrueB. FalseQ.4: A 1-kg particle is attached to the end of a rope (J). It rotates in a vertical circle of radius 1 m.When the particle is at the lowest point (bottom) of the circle, its speed is 15 m/s. The tension (in N)in the rope at this point is:В. 83.2C. 234.8D. 25.7E. 109.8A. 95.6Q.5: A force F = (3i +4j) N acts on a particle that moves from the origin to the point (2,1,3) m.%3DThe work (in Joules) done on the particle by this force during this displacement is:C. 25E. ZeroD. 10Q.6: True or False:"The work done by any nonconservative force through any closed path is alwayszero".A. TrueA. 16В. 18B. False
