What is the magnitude and direction of an electric field that exerts a 1.70×10-5 N downward force on a -1.50 µC charge? JE| = Direction O Downward O Upward To the right

A -0.004 C charge is located in an electric field with magnitude 40 N/C. How much force does the charge feel due to the electric field? O 0.28 N O 0.16 N O 0.34 N O 0.22 N

Point charges q1=q2=6.91⨯10-9C are fixed on the y-axis at y = 85.9m and y = -85.9m. There is a charge q3 with 3.90⨯10-9 C at x=8.35m, y= -0.365 .  The point P is at x=8.35m, y=0. What is the vertical (y) component of the total electric field at P, due to all three charges in Newtons/Coulomb? (Use the convention that positive values indicate an upwards electric field and negative values indicate a downward force.) Calculate to 1 decimal place. You must draw and label a diagram.

What is the force on a -30 µC charge in a 200-N/C electric field? The electric field points to the right. O 0.06 N to the right O 0.006 N to the right 0.006 N to the left O 0.06 N to the left
