A uniform rectangular plate is 5 cm wide and 7 cm tall. A 10 N force acts vertically upwards at the top right corner, and a 10 N force acts vertically downwards at the centre of the plate. Which additional couple will bring the plate into rotational equilibrium?
- A 5 N upward force at the top-left corner and a 5 N downward force at the bottom-right corner
- A 10 N upward force at the centre and a 10 N downward force at the bottom-left corner
- A 5 N force to the right at the top-right corner and a 5 N force to the left at the bottom-left corner
- A 10 N force to the left at the top-left corner and a 10 N force to the right at the bottom-right corner
