## Introduction Mutually perpendicular electric and magnetic field is generally referred to as Cross field. In this document we work out the trajectory of a charged particle in a cross field. The …
## Introduction In most simplified scenarios we ignore the role of air drag on the body under the influence of gravitataion. A good approximation for the air drag force is that it is proportional to …
