Question

A
small square with sides measuring 4.5 mm lies in tje xy plane.
Along one diagonal are duplicate charges of 10 nC at the vertices.
Along the other diagonal are duplicate charges of 25 nC. Calculate
the electeic field at a point 10 mm above the square along the
y-axis

Answer #1

Two long, parallel, current-carrying wires lie in an
xy-plane. The first wire lies on the line y =
0.310 m and carries a current of 25.5 A in the +x
direction. The second wire lies along the x-axis. The
wires exert attractive forces on each other, and the force per unit
length on each wire is 300 µN/m. What is the
y-value (in m) of the line in the xy-plane where
the total magnetic field is zero?

A square conducting loop of side length a = 11 cm sits in the
xy-plane. A uniform magnetic field of strength B = 0.5 mT points
along the positive y-axis. A current of I = 0.3 mA is run through
the loop.
a) Find the net force on the loop.
b) Find the torque on the loop.
c) What is the magnetic dipole moment of the current loop?
d) Find the magnitude of the force on one of the x-direction...

Calculate the magnitude of the electric field at one corner of a
square 1.52 mm on a side if the other three corners are occupied by
4.25×10−6 CC charges.
What is the direction of the electric field at the corner?
along the side of the square between the corner and one of the
charges outward of the charge
along the side of the square between the corner and one of the
charges toward the charge
along the line between the...

C) An electric dipole is formed from two
charges, ±q, spaced 1.30 cm apart. The dipole is at the origin,
oriented along the y-axis. The electric field strength at
the point (x,y)=(0cm,10cm) is 330 N/C .
- What is the charge q? Give your answer in nC.
- What is the electric field strength at the point
(x,y)=(10cm,0cm)? Express your answer with the appropriate
units.
D) A small glass bead charged to 4.5 nC is in the plane that
bisects...
