Answer 1

Answer:

The force will decrease when plastic is introduced.

F= Fⁿ/k [Dielectric constant]

Here, due to plastic k will increase, so F will decrease.

Explanation:

hope it helps✌️

Answer 2

Answer:

⇒ Equal parts having resistance

                $\frac{18}{3} = 6 \: ohms$

⇒ Equivalent resistance in parallel,

$\frac{1}{R} = (\frac{1}{6}) + (\frac{1}{6}) + (\frac{1}{6} ) = \frac{3}{6} = \frac{1}{2}$

⇒ E quivalent resistance, (reciprocal)

        $\frac{1}{2} (reciprocal) = \frac{2}{1} = 2$
