Question

A light string passes over a frictionless pulley. To one of its ends, a mass of 6 kg is attached. To its other end, a mass of 10 kg is attached. The tension in the string will be

• A. $\frac{g}{2}$
• B. $\frac{5g}{2}$
• C. $\frac{10g}{2}$
• D. $\frac{15g}{2}$

Answer 1

The correct option is D $\frac{15g}{2}$

$T-6g=6a$
$10g-T=10a\Rightarrow T=\frac{15g}{2}$
