Question

A thin rod of length L=80 cm carries a total charge of +5 nC uniformly distributed over its left half and -5 nC over its right half. Find the electric field on the axis of the rod at distance r=400 cm from its rightmost end. What is the magnitude of the electric field at point P. (N/C)?

Answer #1

A thin insulating rod of length L has a charge Q spread
uniformly along it. Point P is at a distance R from the middle
point of the rod.
What is the magnitude of the electric field, E, at point
P?

A total charge Q is uniformly distributed, with surface charge
density, over a very thin disk of radius R. The electric field at a
distance d along the disk axis is given by E where n is a normal
unit vector perpendicular to the disk. What is the best
approximation for the electric field magnitude E at large distances
from the disk?

A 10-cm-long thin glass rod uniformly charged to 13.0 nC and a
10-cm-long thin plastic rod uniformly charged to - 13.0 nC are
placed side by side, 4.50 cm apart. What are the electric field
strengths E1 to E3 at distances 1.0 cm, 2.0 cm, and 3.0 cm from the
glass rod along the line connecting the midpoints of the two
rods?
1) Specify the electric field strength E1. Express your
answer with the appropriate units.
2) Specify the electric...

A thin rod of length L is non-uniformly charged. The charge
density is described by the expression λ=cx, where c is a constant,
λ is the charge per length, and x is the coordinate such that x=0
is one end of the rod and x=L is the other. Find the total charge
on the rod and the electric potential at a field point just
touching the rod at the x=0 end.

A very thin wire of length L, having a total charge of Q
-uniformly distributed- lies along the x-axis, with it's right end
at x=L/6 A: Draw a FBD B: Label all known and unknown variables. C:
Set up an integral to determine the electric field at a point on
the y-axis where y=10 cm. above the wire. Integral should be in
terms of L,Q,H, the integration variable and physical constants. Do
not evaluate the integral but instead explain your...

Positive electric charge QQ is distributed uniformly along a
thin rod of length 2aa. The rod lies along the xx-axis between
x=−ax=−a and x=+ax=+a (Figure 1). Calculate how much work you must
do to bring a positive point charge qq from infinity to the point
x=+Lx=+L on the xx-axis, where L>aL>a.
What does your result for the potential energy U(x=+L) become in
the limit a→0? Express your answer in terms of some or all of the
variables Q, q, a,...

A thin, non conducting rod with length L lies along the positive
X-Axis with one end at the origin. The rod carries a charge
distributed along its length of λ(x) = bx/L. Determine the electric
potential along the X-Axis at the point x = 2 cm if L = 1 cm and b
= 50 pC/m. Answer = (0.17 V)

A 10-cm-long thin glass rod uniformly charged to 14.0 nC and a
10-cm-long thin plastic rod uniformly charged to - 14.0 nCare
placed side by side, 3.80 cm apart. What are the electric field
strengths E1 to E3 at distances 1.0 cm, 2.0 cm,
and 3.0 cm from the glass rod along the line connecting the
midpoints of the two rods?

A straight, nonconducting plastic wire 9.50 cm long
carries a charge density of 100 nC/m distributed uniformly along
it's length. It is lying on a horizontal tabletop.
A. Find the magnitude and direction of the electric field this wire
produces at a point 4.50 cm directly above its midpoint.
