AP EAMCET · PHYSICS · Laws of Motion
The coefficient of friction between object and substance, if we need to move an object of weight \(150 \mathrm{~N}\) on a horizontal surface with a force of \(75 \mathrm{~N}\), is
- A 0.8
- B 0.5
- C 0.7
- D 0.9
Answer & Solution
Correct Answer
(B) 0.5
Step-by-step Solution
Detailed explanation
For the given object to move \[ \begin{aligned} & \mu \mathrm{mg}=\mathrm{F} \\ \Rightarrow & \mu \times 150=75 \\ \Rightarrow & \mu=0.5 \end{aligned} \]
