In the arrangement shown pulley is ideal and string is massless. 5 kg block is moving on the horizontal which is smooth. When θ is 37° acceleration of 5 kg and 10 kg blocks are a 1 and a 2 . Tension in string connecting blocks is T and the total force applied by this string on pulley is F. Then: (g = 10 m/s 2 )
(Values of quantities in column II are in SI units)
Column I | Column II |
(i) a1 | [A] 5.6 |
(ii) a2 | [B] 43.75 |
(iii) T | [C] 7 |
(iv) F | [D] 78.26 |

(i)-[C], (ii)-[A], (iii)-[B], (iv)-[D]
Sol. a 1 cos 37° = a 2
4a 1 = 5a 2 ... (1)
100 – T = 10a 2 ... (2)
T cos 37° = 5a 1
T = 
a 1 ... (3)
and F =
