A6 n and a 10 n force act on an object. the moment arm of the 6 n force is 0.2 m. if the 10 n force produces five times the torque of the 6 n force, what is its moment arm?

The moment arm is 0.6 m

Explanation:

Given that,

First force

Second force

Distance r = 0.2 m

We need to calculate the moment arm

Using formula of torque

So, Here,

We know that,

The torque is the product of the force and distance.

Put the value of torque in the equation

Where, =First force

=First force

=Second force

= distance

Put the value into the formula

Hence, The moment arm is 0.6 m

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
