A uniform current density of 5050 A/m2\(\text{A/m}\)^2 crosses a flat surface of area 0.0200.020 m2\(\text{m}\)^2. The angle between J→\(\overrightarrow{J}\) and the surface normal is 6060°. What current passes through the surface?

A uniform current density of $50$ ${A/m}^{2}$ crosses a flat surface of area $0.020$ $m^{2}$ . The angle between $\vec{J}$ and the surface normal is $60$ °. What current passes through the surface?
