In the figure `A` and `B` are two blocks of mass `4 kg` and `2 kg` respectively attached to the two ends of light string passing overa disc `C` of mass `40 kg` and radius `0.1 m`. The disc is free to rotate about a fixed horizontal the string does not string does not slip over the disc. Find.
(i) The linear acceleration of mass `B`.
(ii) the number of revolutions made by the disc at the end of `10 sec`. from the start.
(iii) the tension in teh string segment supporting the block `A`.
.

Answer

`5000//26 pi `
