Neco 2022 Physics Question 4
Practice objective / multiple choice question 4 from the 2022 Neco Physics examination.
A proton (charge \(q = +1.6\times10^{-19}\) C) enters a region where a uniform electric field of magnitude \(E = 2.0\times10^{3}\) N C(^{-1}) points upward and a uniform magnetic field is perpendicular to the electric field. The proton's velocity is horizontal to the right with magnitude \(v = 2.0\times10^{6}\) m s(^{-1}). What magnitude of magnetic field \(B\) (in tesla) is required so that the proton travels through the region undeflected? State your answer in scientific notation to two significant figures.
