As shown in figure two blocks \( \mathrm{A} \) and \( \mathrm{B} \) of mass \( 1 \mathrm{~kg} \) each are connected by an ideal string that passes over a smooth pulley that is fixed on a smooth fixed wedge as shown. If the ratio of normal reaction on block A and on block \( B \) is \( 4 / 3 \) then -
(1) \( \cos \theta=\frac{4}{5} \)
(2) \( \sin \theta=\frac{4}{5} \)
(3) Acceleration of blocks is \( \frac{g}{10} \mathrm{~m} / \mathrm{s}^{2} \)
(4) Acceleration of blocks is \( \frac{g}{5} \mathrm{~m} / \mathrm{s}^{2} \)
