An electron is accelerated from rest by potential difference of 350volts it then enters a uniform magnetic field of magnitude 200mt with its velocity perpendicular to the field calculate the speed of eletron the radius of the path in the magnetic field

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
