Step-by-step explanation:
To get 10% of a number, you need to divide the number by 10.
35,000 ÷ 10 = 3,500
Answer:
Step-by-step explanation:
We are given that
Charge of atomic nucleus,q=+40 e=
Because
1 e=
Charge of atomic nucleus=
Distance of charge form the center of nucleus=r=1 m
We have to find the magnitude of electric field at distance r
Where K=
Using the formula
Using identity
Hence, the magnitude of electric field=
1/2 to the second power I'm sure is 1/4
