Understanding the Answer
Let's break down why this is correct
The maximum static friction can only be as large as the product of the coefficient of static friction and the normal force. Other options are incorrect because This answer assumes the static friction could equal the entire parallel component of gravity, but friction can only reach the product of the coefficient and the normal force; Here the mistake is adding the normal and parallel forces together.
