(a) find the magnitude of the electrostatic force between a na+ ion and a cl− ion separated by 0.83 nm.

Explanation:

Given that,

Distance between charges,

We need to find the electrostatic force between a and ion.

Charge on

Charge on

The electrostatic force is given by :

So, the magnitude of electrostatic force between two ions is . Hence, this is the required solution.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
