sir,in this question why BD=(20)*2-(16)*2?and we have write sin theeta is equal to sin 90-35?
sir,can we say that the particle having magnetic field more than B0(min) and velocity more than V0 is able to srike the target?please explain
sir,the magnetic field in between two stright wires is not constant?as in between two loops?
sir,is these conditions are only for prependicular electrical and magnetic fields?what will happen if electric and magnetic fields are in same direction?
Sir pls me with 4th and 5th question
