Two small objects each with a net charge of q (positive) exert a force of magnitude f on each other. we replace one of the objects with another whose net charge is 4q. the original magnitude of the force on the q charge was f; what is the magnitude of the force on the q now?
a. 16f
b. 4f
c. f
d. f/4

option B

Explanation:

we know,

Force between two charge is calculated by

r is the distance between the two charges

k is Coulomb constant.

give two small object with charge Q

now, Force

......(1)

now,

New force if another charge is equal to 4 Q

now from equation 1

Hence, the correct answer is option B

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
