Magnetic Effects of Current and Magnetism: JEE Main 2024 Physics question

An electron moves through a uniform magnetic field $\vec{B}=B_0 \hat{i}+2 B_0 \hat{j} T$. At a particular instant of time, the velocity of electron is $\vec{u}=3 \hat{i}+5 \hat{j} \mathrm{~m} / \mathrm{s}$. If the magnetic force acting on electron is $\vec{F}=5 e \hat{k} N$, where $e$ is the charge of electron, then the value of $B_0$ is _________ $T$.
