Answer 1

6.48 × 10^-5 N

Step-by-step explanation:

To determine the electrical force between the two balloons separated by two different charges we can use coulomb's law.

Coulomb's law states that the force of attraction b/w two charges is directly proportional to the product of the two charges and inversely proportional square of the distance between them.

The Equation for coulomb's law is :

`\boxed{{\sf {F = K (q_1 q_2)/(r^2)}}}`

Here K is constant of proportionality whose value is equal to
`\sf9 * 10^9 \: N C^(-2)m^2`

`\sf q_1 = 12 * 10^(-8) \: and \: q_2 = 6 * 10^(-8)`

r is distance between two charges i.e 100 cm = 1 m

On solving we get

`\sf \: F = \frac{9 * {10}^( 9) ( 12 * {10}^( - 8)) ( 6 * {10}^( - 8) ) }{ {1}^(2) } \\ \\ \sf \: F = \frac{648 * {10}^(9) * {10}^( - 8) * {10}^( - 8) }{1} \\ \\ \sf \: F = 648 * {10}^( - 7 )\\ \\ \sf \: F =6.48 * {10}^( - 5) \: N`

Therefore the electrical force between the two balloons separated by two different charges is 6.48 × 10^-5 N
