Two obiect accumulated a charge of
4.5 uc and another a charge n. 2. 8
HC. These two objects are separated
by a distance of 2.5 cm. Calculate the
magnitude of the electric force
between these two objects.
A.181.24 N
B.4.53 N
C. 1.81 x 10^14 N
D. 2.02 x 10^-8 N

A. 181.24 N

Explanation:

The magnitude of hte electrostatic force between two charged objects is given by the equation

where

k is the Coulomb's constant

q1, q2 are the magnitudes of the two charges

r is the separation between the charges

In this problem, we have:

is the magnitude of the 1st charge

is the magnitude of the 2nd charge

r = 2.5 cm = 0.025 m is the separation between the charges

Therefore, the magnitude of the electric force is:

So, the closest answer is

A) 181.24 N

b

explanation:

bc its just b

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
