The force of attraction / repultion of two charges is given by F = KQ1Q2 / d^2; where K is the Coulumbs constant, Q1 is the charge on charge 1, Q2 is the charge on charge 2, d is the distance of the two chardes apart.
Thus,
KQ1Q2 / 4 = 2 x 10^-5
KQ1Q2 = 4 x 2 x 10^-5 = 8 x 10^-5
When the distance between the charges was reduced to 1 meter.
F = KQ1Q2 / d^2 = 8 x 10^-5 / 1^2 = 8 x 10^-5
Therefore, option C is the correct answer.
Answer:
1.it also hleps us to became doctors becuase without physics you can't be a doctor
2.physics needs to be steady whether you like it or not it helps you in life so everybody must study physics no matter is in Uganda USA and plenty more countries there must be physics to dare to be studied
A) Volume of cuboid = length *breadth*height
=10*2*2=40cm^3
B)time period of one pendulum = no.of oscillations/time= 10/8= 5/4
C) 3 bars
Answer:
The correct answer is - true.
Explanation:
Changes in the higher authorities or managers or coworkers can be a warning sign before a layoff, however, a company or organization needs to give an official notice before a particular time period before the layoff.
The layoff is a temporary suspension or permanent termination from the employment of an employee due to reasons related to business such as reducing manpower or staff and less work in the organization. These reasons can lead to a change in the behavior of the managers, coworkers, and subordinates.
