Hello gents/ladies(adsbygoogle = window.adsbygoogle || []).push({});

I've been pondering on how to calculate the force (N) generated by a radiative body.

My enquiries are still in the initial stage, and it has been a few years since i did any serious physics, hence I was wondering if anyone could help me with calculating:

- the force generated by a body with a particular emissivity given an energy input and;

- calculate the rotational torque generated by such a body (although i assume this is the standard torque calculation once you have the force.

Thank you

Matthew
