it contains many other gases and it contains mercury vapour
Answer:
option b
Explanation:
There is an object pulled inward in an electric field.
We have to find out of the four options given which is true.
a) The object has a neutral charge is false since when electric field pulls the object inward, there is a charge inside.
b) The object has a charge opposite that of the field, this option is correct since there will be an equal and opposite charge created by the object
c) The object has a negative charge will be correct only if the original charge was positive hence wrong
d) The object has a charge the same as that of the field is incorrect since this would be opposite the charge
So only option b is right

The gravitational field strength on the moon is 
of the gravitational field strength on the earth
<u>On the earth:</u>
the gravitational field strength (g) is determined as:
where:
- G: the gravitational constant
- m: the mass of the earth
- r: the radius of the earth
<u>Then on the moon:</u>
![g=[tex]\frac{1}{6}](https://tex.z-dn.net/?f=g%3D%5Btex%5D%5Cfrac%7B1%7D%7B6%7D)
*9.8=1.6 N/kg[/tex]
<u>The answer will be</u> : A.1.6 N/kg
