Why were the outnumbered spanish conquistadors able to so easily defeat the natives of south and central america?

They had a vastly superior technology such as steel and guns, as well as diseases. The locals got diseases from Europe because they didn't have the immunity built up so they died by the thousands while the conquistadors thrived. It was easy for them to conquer the locals.

As we can see here the lever has two forces at two ends

1. 300 N

2. 200 N

now we need to find the Torque on the lever about the fulcrum

so we will have

1. clockwise torque due to force at right end is

2. counterclockwise torque due to force at left end

so as per above calculations we can see that net torque on the lever is clockwise as it has more torque in clockwise direction

so it will rotate clockwise
