Question

A force of $6kg.wt$ and $8kg.wt$ can be applied together to produce the effect of a single force of:

• A. $20kg.wt$
• B. $15kg.wt$
• C. $11kg.wt$
• D. $1kg.wt$

Answer 1

Answer: (C)

$11kg.wt$

Maximum value can be $F_{max}=8+6=14kg.wt$, minimum can be $F_{min}=8-6=2kg.wt$. Thus $11kg.wt$ is the only possible option.
