Question

2d The charges in the figure above both have a magnitude of 6.20 nC, and the distance d is 5.40 cm. What is the magnitude of the electric field at the dot? 2.26E+04N/C o 2.29E+04 N/C 2.11E+04N/C 2.42E+04 N/C Question 2 In the figure above, charge A is-235 nC, charge B is 4.70 nC, and charge C is 2.35 nC. If x 4.00 cm and y 8.00 cm, what is the electric field at the dot? 1.27x104 N/C, 19.4° clockwise from the positive rais 1.69x104 N/C, 19.4° counter-clockwise from the positive xaxis 1.27x104 N/C 3899 clockwise from the positive raxis 1.69x104 N/C 3899 clockwise from the positive raxis Question3 A-1.00 nC charge of mass 1.10x106 kg is released from rest 2.50 mm above a very large plane of positive charge. The charge accelerates toward the plane and collides with a speed of 3.00 m/s. What is the surface charge density of the plane? e 3.50x105 C/m2 O 1.17x105 C/m2 3.33x10-7 C/m2 o 1.75x105 C/m2

Q1. The charges in the figure above both have a magnitude of 6.20 nC, and the distance d is 5.40 cm. What is the magnitude of the electric field at the dot?

Q2.In the figure above, charge A is -2.35 nC, charge B is 4.70 nC, and charge C is 2.35 nC. If x = 4.00 cm and y = 8.00 cm, what is the electric field at the dot?

Q3.A -1.00 nC charge of mass 1.10×10^-6 kg is released from rest 2.50 mm above a very large plane of positive charge. The charge accelerates toward the plane and collides with a speed of 3.00 m/s. What is the surface charge density of the plane?
