Question 258: Laws of Motion

Question

Two masses as shown in the figure are suspended from a massless pulley. The acceleration of the system when masses are left free is

Accepted Answer

Let T be the tension in the string.
$$ 	herefore $$ 10g Ã¢ÂÂ T = 10a     ....(i)
T Ã¢ÂÂ 5g = 5a             ....(ii)
Adding (i) and (ii),
$$5g = 15a \Rightarrow a = {g \over 3}m/{s^2}$$

Answer

$${{2g} \over 3}$$

Answer

$${g \over 3}$$

Answer

$${g \over 9}$$

Answer

$${g \over 7}$$.
