Consider4 the situation shown in figure. Bothe the pulleys and the string are light and all the surfaces are friction less. a. Find the acceleration of the mass M. b. Find the tension in the string c. Calculate the force exerted by the clamp on the pulley A in the figure.

Explanation

`T+1a=1g`……………i.
And `T=1a` ………..ii.
From equation i and ii we get
` 1a+1a=1g`
`rarr 2a=g`
`rarr a= g/2 = 10/2 =5m/s^2`
From equation ii `T=1a=5N`
