उत्तर
Components of the vectors
(a) T – mg = ma
(b) `overlineT_x + overlineF_x = overlineA_x + overlineB_x` (Or)
`overlineT_y + overlineF_y = overlineA_y + overlineB_y`
(c) `overlineT_x - overlineF_x = overlineA_x + overlineB_x` (Or)
`overlineT_y - overlineF_y = overlineA_y + overlineB_y`
(d) T + mg = ma
