Question

a rope of length 10m and linear density 0.5kg/m is lying length wise on a smooth horizontal floor. It is pulled by a force of 25N . The tension in the rope at a point 6m away from the point of application is
1)20 2)15 3)10 4)5 ​

Answer 1

Answer is

10

Mass of rope = 23 votes

mass of rope = 10×0.5 = 5kgForce = 25Na = F/m = 25/5 = 5 m/s2mass of rope remaining after 6m = 4m × 0.5 kg/m = 2kga = 5 m/s2 Tension at point 6m from
