Hello, I need help with an integration. I found the torque on a ball of charge with varying charge density(dependant on the radial component) in a uniform magnetic field. I got(adsbygoogle = window.adsbygoogle || []).push({});

Integral[ (wxr)(r.B)(density)(r^2) sin(phi) d(theta) d(phi) dr, {r, 0,R}] where wxr is the cross product of the angular velocity and the radial component, r.B is the dot product between the radial component and the magnetic field. The trouble is integrating this monster, can anyone help?
