Question
The figure shows a block of mass m placed on a smooth wedge of mass M. Calculate the value of M¢ and tension in the string, so that the block of mass m will move vertically downward with acceleration 10 m/s2
(Take g = 10 m/s2)

- the value of M¢ is
- the value of M¢
- the value of tension in the string is
- the value of tension is
The correct answer is: the value of M¢ is

In the figure, a man of true mass M is standing on a weighing machine placed in a cabin. The cabin is joined by a string with a body of mass m. Assuming no friction, and negligible mass of cabin and weighing machine, the measured mass of man is (normal force between the man and the machine is proportional to the mass)
