The magnitude of the force exerted by the chain is 36.1 N.

Resultant forces

The magnitude of the force exerted by the chain must balance the force exerted by the ring and weight of the pot.

The magnitude of the force exerted by the chain is calculated by applying Pythagoras theorem;

[tex]F_3^2 = F_1^2 + F_2^2\\\\F_3 = \sqrt{F_1^2 + F_2^2} \\\\F_3 = \sqrt{20^2 + 30^2} \\\\F_3 = 36.1 \ N[/tex]

Thus, the magnitude of the force exerted by the chain is 36.1 N.
