Two balloons are charged with an identical quantity and type of charge: -6.25 nanoCoulombs (10-9). They are held apart at a separation distance of 61.7 cm (make sure to use METERS!). Determine the magnitude of the electrical force of repulsion between them.

force between both the balloons is  

Explanation:

It is given charge on both balloons are same and equal to

Separation between both the balloons

According to Coulomb's law force between two charges is given by

Therefore force is equal to

So force between both the balloons is

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
