Gce Model Questions Vol1 2020 Physics Question 12
Practice objective / multiple choice question 12 from the 2020 Gce Model Questions Vol1 Physics examination.
A block of mass \(5.0\,\text{kg}\) rests on a rough inclined plane that makes an angle of \(30^{\circ}\) with the horizontal. The coefficient of static friction between the block and the plane is \(\mu_{s}=0.30\). A horizontal force \(F\) is applied to the block (pushing up the plane). (a) Find the minimum magnitude of \(F\) required to start moving the block up the plane. (b) Using the same force \(F\) found in part (a), the block is placed on a second plane of unknown angle \(\theta\). The block is now on the verge of sliding down the plane. Determine \(\theta\).
