A strong plank 8.0 m long and having a negligible mass is supported by steel cables from both ends. A jaguar with a weight of 800 N stands 2.0 m from one end. What is the tension force in the cable farthest from the jaguar?

a. 120 N

b. 200 N

c. 240 N

d. 400 N

e. 600 N

f. 800 N

2. Relevant equations

3. The attempt at a solution

I'm not sure how to solve this problem. Is it a two dimensional problem? I'm not told whether the bridge bends down because of the jaguar's weight. Now, to find the tension force, I know it's m times a, but since the jaguar is not moving, the jaguar's pull on the rope (the tension force) is only going to be the force of gravity which the jaguar experiences (in the -z direction). Is this then simply 800 N? But how do I take distances into account when calculating tension force? Thanks for any help.
