Question

Physics
please help
its physic based on the law of movement​

Answer 1

Step-by-step explanation:

4) The net torque on the on the meter stick is equal to zero in order to have no rotation.

`\tau_(1) = \tau_(2)`

`F_(1)d_(1) = F_(2)d_(2)`

`(8 \:N)(0.3\: m) = F_(2)(0.1 \:m)`

`F_(2) = ((8 \:N)(0.3 \:m))/((0.1 \:m)) = 24 \:N`

5) We are going the same equations in #4 here.

`F_(1)d_(1) = F_(2)d_(2)`

`(500 \:N)(2.4 \:m) = F_(2)(3.0 \:m)`

`F_(2) = ((500 \:N)(2.4 \:m))/((3.0 \:m)) = 400 \:N`
