Practice Questions

Question 1

A force of $10 \, \text{N}$ is acting at an angle of $30^\circ$ to the horizontal. What is the horizontal component of this force?

Question 2

If two forces of $5 \, \text{N}$ and $12 \, \text{N}$ are acting at right angles to each other, what is the magnitude of their resultant force?

Question 3

A particle is in equilibrium under the action of three coplanar forces which are $8 \, \text{N}$, $6 \, \text{N}$, and $x \, \text{N}$. If the forces are directed such that the sum is zero, what is the value of $x$?

Question 4

If a force of $20 \, \text{N}$ acts at an angle of $60^\circ$ to the horizontal, what is the vertical component of the force?

Question 5

A force of $30 \, \text{N}$ is directed at an angle of $45^\circ$ from the horizontal. What is the value of the vertical component of the force?
