H

A lamp hangs at rest from a ceiling by a single cable.

The weight of the lamp is 20 N.

Which statement about the forces on the lamp is correct?

[1]
A

The tension is 20 N20\ \text{N}20 N upwards and the resultant force is zero

B

The tension is 40 N40\ \text{N}40 N upwards and the resultant force is 20 N20\ \text{N}20 N upwards

C

The tension is 20 N20\ \text{N}20 N upwards and the resultant force is 20 N20\ \text{N}20 N downwards

D

The tension is zero and the resultant force is 20 N20\ \text{N}20 N downwards
