A disc 'A' of mass M is placed at rest on the smooth incline surface of inclination theta. A ball B of mass m is suspended vertically from the centre of the disc. A by a light inextersible string of length l as shown in the figure. If the acceleration of the disc B immediately after the system is released from rest is ((M+km)gsin^(2)theta)/(M+msin^(2)theta). Find k. |

Answer» SOLUTION :`Mgsintheta+Tsintheta=Ma` `mg-T=ma SINTHETA` solving, we GET `a=((M+m)G sin^(2)theta)/(M+msin^(2)theta)`
