Using constraint method find the relation between acceleration of 1 and 2 |
|
Answer» SOLUTION :At any instant of time let `x_(1)"and " x_(2)` the displacement of 1 and 2 from a fixed line Then , `x_(1)+x_(2)`= constant or `x_(1)+x_(2)=l `(length of string) Differentiating with respect to time , we have `v_(1)+v_(2) =0 "or" v_(1)=-v_(2)` Again differentiating with respect to time , we get `a_(1)+a_(2)=0 "or" a_(1)=-a_(2)` This is the required RELATION between `a_(1)"and " a_(2)` .i.e, accelerations of 1 and 2 are equal but in opposite DIRECTIONS .
