This question is for checking students understanding of resolving forces using Newton’s Second Law F = ma
a) Student has misunderstood how to use the parity of the force components.
b) Correct solution
c) Student has used the incorrect component of the weight force
d) The student has assumed equilibrium rather than acceleration.
e) The student has not split the weight force into components; does not understand that only parallel components are considered
f) The student has not understood that perpendicular forces have no effect on the resolution.
More to follow soon I hope!
