Answer #1

**a. Formula Used:**

**Magnitude of Electric Field
at a distance 'r' from the charge is given by :
**

Two point charges of +30.0 μC and -9.00 μC are separated by a
distance of 20.0 cm. What is the intensity of the electric field E
midway between these two charges? A. 18.1x106 N / C, towards
positive charge b. 35.1x106 N / C, towards negative charge c. 0 N /
C d. 18.1x106 N / C, towards negative charge

Two point charges, -25?C and +60?C , are
separated by a distance of 22.0cm .
What is the magnitude of the electric field at a point halfway
between the two charges?

15.3 Two equal point charges are separated by a distance of 23
cm. The magnitude of the force that one charge exerts on the other
is 18 N. What is the charge?
15.4 A 5 μC charge and a 3 μC charge are separated by some
distance. If the magnitude of the force that one charge exerts on
the other is 27 N, what is the distance between the two
charges?

Two point charges, −15.0 μC and +12.0 μC, are kept 6.80 cm
apart.
What is the magnitude of the electric field midway between the
two point charges?

Two point charges, Q1 = -30 ?C and Q2
= 56 ?C , are separated by a distance of 12 cm. The
electric field at the point P (see the figure(Figure 1)) is zero.
How far from Q1 is P?

Two point Charges, q and -q, are separated by a distance d, both
being located at a distance d/2 from the infinite conducting plane.
What is the magnitude of the electric force action on each charge?
Find the magnitude of the electric field at the midpoint between
these charges?
Reference: In this instance the Conducting plate Separates -q
and q (which is d distance apart above the conducting plate). The
conducting plate is d/2 distance below the charges -q and...

Two point charges, Q1=−35μCaaaa andQ2=44μCare separated by a
distance of 12 cm. The electric field at the point P is zero
How far From Q1 is p

Two point charges, A and B, are separated by a distance of 19.0
cm . The magnitude of the charge on A is twice that of the charge
on B. If each charge exerts a force of magnitude 46.0 N on the
other, find the magnitudes of the charges.

Two point charges are separated by a distance r. If the
separation is reduced by a factor of 10.2, by what factor does the
electric force between the two charges increase?

Two point charges, A and B, are separated by a distance of 23.0
cm23.0 cm . The magnitude of the charge on A is twice that of the
charge on B. If each charge exerts a force of magnitude 48.0 N48.0
N on the other, find the magnitudes of the charges.
