V/m My Answers Chee Part B What is the drection of electric feld in this case? MacBook Air

Explanation / Answer

We know that the magnitude of electric field is

F= q(VxB)

F= (-0.32 * 10^-9).(5.85*10^3 J)x (-1.35K)

F= (2.52 * 10^-6)i v/m

We know that JxK = i

This implies the direction of electric field is along positive i (+i)
