A proton beam passes without deviation through a region of space where there are uniform transverse mutually perpendicular electric and magnetic fields with \( E=120 \mathrm{kV} / \mathrm{m} \) and \( B=50 \mathrm{~m} \) T. Then the beam strikes a grounded target. Find the force which the beam acts on the target if the beam current is equal to \( 0.80 \mathrm{~mA} \). 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
