In order to delete a file, it is required to first select the file which you want to delete and then select 'delete' from the file menu. It will then ask you to confirm the deletion which will be required in order to complete the file deletion process.
It isn't required to click on the X at the top right of the screen or to open the file you want to delete as these steps aren't relevant to the deletion process.
Hence, the statements which describe the steps you need to take in order to delete a file are as follows:
- Confirm the deletion.
- Select Delete from the File menu.
- Select the file you want to delete.
We have that the electric field at the center of the metal ball due only to the charges on the surface of the metal ball is
![E=7*10^{9}N/C](https://tex.z-dn.net/?f=E%3D7%2A10%5E%7B9%7DN%2FC)
From the question we are told that
A solid metal ball of radius 1.5 cm
bearing a charge of -15 nC is located near a hollow plastic ball of radius 1.9 cm bearing
uniformly distributed charge of -7 nC
The distance between the centers of the balls is 9 cm
Generally the equation for the electric field is mathematically given as
![E=\frac{kq_2}{d^2}\\\\E=\frac{(9*10^9)7*10^{-2}}{9*10^{-2}}\\\\](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bkq_2%7D%7Bd%5E2%7D%5C%5C%5C%5CE%3D%5Cfrac%7B%289%2A10%5E9%297%2A10%5E%7B-2%7D%7D%7B9%2A10%5E%7B-2%7D%7D%5C%5C%5C%5C)

To find the scientific notation, you need to divide at the decimal by the power of 10. So since there are 2 powers of 10, what you want to do is move the decimal 2 places to the left which will give you: .054
