e force acting between two charged particles A and B is 5.2 × 10-5 newtons. Charges A and B are 2.4 × 10-2 meters apart. If the

charge on particle A is 7.2 × 10-8 coulombs, what is the charge of particle B? (k = 9.0 × 109 newton·meters2/coulomb2)

The force acting between the particles is

F=k \frac{Q_{1}Q_{2}}{r^2}
Then
Q_{2}= \frac{5.2 \times 10^-^5 \times 0.024^2}{ 9.0 \times 10^9 7.2 \times 10^-^8} =4.622 \times 10^-^1^1C

i think your answer is this: the objects have no interactive with each other.

Explanation:

if you think about it tissue paper doesn't really have a static electrical charge if it does it is very weak so therefore cannot really attract or repel anything.

Two points are given in polar coordinates by : (r, θ) = (2.60 m, 50.0°)
alukav5142 [94]

Answer:

The distance between the 2 points is 4.6558 meters.

Explanation:

The distance between 2 points (r_1,\theta _1),(r_2,\theta _2) is given by

d=\sqrt{r_{1}^{2}+r_{2}^{2}-2r_1\cdot r_2cos(\theta _2-\theta _1)}

In our case the given 2 points are (2.60,50.0^{o}),(3.60,-46.0^{o}) hence the distance is

d=\sqrt{2.60^{2}+3.60^{2}-2\cdot 2.60\cdot 3.60\cdot cos(-46.0-50)}\\\\\therefore d=4.6558m
