Are vectors a1 and a2 perpendicular? If not, what is the angle between them? The angle is 120 degrees

Describe the procedure for adding a1 and a2 using vector resolution.

Vectors are added by placing them at the end of the second vector to the tip of the first one.

Which of the vector components shown has a negative value? Explain your answer.

Which of the two displacement vectors has a larger vertical component?

Which of the two displacement vectors has a larger horizontal component?

What equation would you use to calculate the components of a1?

What equation would you use to calculate the components of a2?

What equation would you use to add anet x and anet y?

What is the resultant of a1 and a2?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
