A velocity selector consists of electric field E→=Ek^ and magnetic field B→=Bj^ with B = 12 mT. The value of E required for and electron of energy 728 eV moving along the positive x-axis to pass undeflected is:(Given. Mass of electron =9.1×10-31kg ) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
