Gce Model Questions Vol1 2020 Physics Question 19
Practice objective / multiple choice question 19 from the 2020 Gce Model Questions Vol1 Physics examination.
An inclined plane makes an angle of \(30^{\circ}\) with the horizontal. A block of mass \(5.0\ \text{kg}\) rests on the plane. The coefficient of static friction between the block and the plane is \(\mu_{s}=0.40\). The block is attached to a light string that is pulled with a force \(F\) acting at an angle of \(20^{\circ}\) above the plane (i.e., the string makes \(20^{\circ}\) with the surface). Using the force diagram shown, determine the minimum magnitude of \(F\) required to start the block moving up the plane.
