1.1Which of the following is a contact force?
Tick () one box.
[1 mark]
Electrostatic force
Gravitational force
Magnetic force
Air resistance
A student pulls down diagonally on a spring that is attached to a
1.2
clamp stand. The spring is stretched with a force of 25 N applied at an angle
of 37° below the horizontal, as shown in the diagram.
Resolve the 30 N force to find its horizontal component.
