Answer:

Explanation:
The force is defined as the negative of the derivative of the potential energy:

If we use the potential energy function given in this problem:

and we calculate the force, we get:

So, the force is

E, 63% of the value. I forget the rationale behind it but I learnt that in engineering. 90% confident for that answer.
Answer:
x = 2
Explanation:
if it was -7 = the square root of both 2x-9 together, it would be false.
if it was square root of just 2x in the equation, the answer is:
x = 2
°°°°°°°°°
-7 = √2x - 9
-√2x = -9 + 7
√-2x = -2
√2x = 2
2x = 4
x = 2
You have to add 1.7 and 2.2 together!
1.7+2.2=3.9μF
