Answer:

q2 = -1.61*10^-5 C.

Explanation:

It was given that,

F = 0.985N

q1 = +8.40 X10-6 C

q2 = ?

r = 1.11 m

k = 9 x 10^9 (standard)

It generally follows that, if force is attractive, charge will be negative.

force, F = kq1q2/r^2

0.985 = 9*10^9*8.40*10^-6*q2/1.11^2

75600q2 = 0.985*1.11^2

75600q2 = 1.2136

q2 = 1.2136/75600 = 1.60529

q2 = -1.61*10^-5 C.

According to Ohm's law, which is stated as I = V + R, which two sentences are true?
Novay_Z [31]

So, If the resistance decreases, then the current increases. Assume voltage is constant.

If the voltage increases, then the current increases. Assume resistance is constant.

Explanation:

According to the ohm's law; I = V/R;

  • If the resistance decreases the current increases assuming that the voltage is constant
  • if the voltage increases, then the current increases assuming that the resistance is constant.

Based on Ohm's law, we know that the current through a metallic conductor is directly proportional to the voltage across the ends.

From the relationship;

                 I = \frac{V}{R}

        we see that  V = IR

These equations affirms that

  • If the resistance decreases the current increases assuming that the voltage is constant based on the second equation

  • if the voltage increases, then the current increases assuming that the resistance is constant based on the first equation.
