A mass $M$ is tied to the top of two identical poles of height $H$ using massless strings of equal length. The mass is at height $h$ above the ground at equilibrium. If the distance between poles is $L$ the tension in each string will be

Options:

Answer:

Solution:

At equilibrium, $M g = 2 T sin θ$
$T = \frac{M g}{2 s i n θ}$ Here, $sin θ = \frac{( H - h )}{( L /2 ) ^{2} + ( H - h ) ^{2}}$ From equation (i) $T = \frac{M g ( L /2 ) ^{2} + ( H - h ) ^{2}}{2 ( H - h )}$
