The electric potential due to a point charge q at the origin is given by
The x-component of electric field is
Answer:
Answer:
2:1 or 2
Step-by-step explanation:
<em>*** </em>(Ratios can be written as " a : b", or can be written as a fraction " a / b".
>> therefore 10/5 can be simplified to 2/1 )<em>***</em>
For every 10 notebooks, there are 5 ballpens.
Therefore, for every 2 notebooks there is 1 ballpen (The simplification).
<u><em>EXTRA: </em></u>
**Also remember that the ratio of notebooks to ballpens cannot be reversed into ballpen to notebook ratio, because this would change the meaning.
2/1 is not the same as 1/2 **
Given:
- Height of cylinder is 18.2 cm
- Radius of cylinder is 3 cm
To Find?
Solution:
Using formula:
- Surface area of cylinder = 2πr (h + r)
Substituting values in the formula:
- Hence, (B) 399.4 cm² is right answer.
