Answer:

magnitude: 100 N direction: east

Explanation:

The electrostatic force between two charges is given by

F=k\frac{q_1 q_2}{r^2}

where

k is the Coulomb's constant

q1 and q2 are the two charges

r is the separation between the charges

In this problem, we have

q_1 = 5 \mu C = 5\cdot 10^{-6} C

q_2 = 2 \mu C = 2\cdot 10^{-6} C

r=3\cdot 10^{-2} m

Substituting into the equation, we find the magnitude of the force

F=(9\cdot 10^9 N m^2 C^{-2})\frac{(5\cdot 10^{-6}C)(2\cdot 10^{-6}C)}{(3\cdot 10^{-2}m)^2}=100 N

Concerning the direction, let's notice that:

- Both charges are positive, so the force between them is repulsive

- The charge q1 is west of the charge q2

- So, the force applied by q1 on q2 must be to the east (away from charge q1)

atroni [7]

Answer:

\huge\boxed{\sf 1.6\ units = 14.4p}

Explanation:

Since,

<h3><u>1 kWh = 1 unit</u></h3>

So,

1.6 kWh = 1.6 units

If,

<h3>1 unit = 9p</h3>

1.6 units = 9p × 1.6

1.6 units = 14.4p

an object is placed at 19.3 cm in front of a diverging lens with a focal length of -18.7 cm. what is the magnification? enter a
Bezzdna [24]

The magnification <u>is 31.16.</u>

Magnification is the process of increasing the apparent size of something rather than its physical size. This increase is quantified by a calculated number, also called the "factor". If this number is less than 1, it means size reduction, sometimes called size reduction or reduction.

u =  -19.3

f = -18.7 cm.

m = f/f-u

    = -18.7/-18.7 +19.3

   <u>= 31.16</u>

The term magnification refers to the size of the image produced by the lens compared to the size of the object. For lenses: Magnification "m" is the ratio of image height to object height. The magnification of a lens is defined as the ratio of image height to object height. It is also given by image distance and object distance. equal to the ratio of image distance to object distance.
