Two charged particles are a distance of 1.62 m from each other. One of the particles has a charge of 7.10 nc, and the other has
k0ka [10]

Answer:

A. F=107.6nN

B. Repulsive

Explanation:

According to coulombs law, the force between two charges is express as

F=(Kq1q2) /r^2

If the charges are of similar charge the force will be repulsive and if they are dislike charges, force will be attractive.

Note the constant K has a value 9*10^9

Hence for a charge q1=7.10nC=7.10*10^-9, q2=4.42*10^-9 and the distance r=1.62m

If we substitute values we have

F=[(9×10^9) ×(7.10×10^-9) ×(4.42×10^-9)] /(1.62^2)

F=(282.4×10^-9)/2.6244

F=107.6×10^-9N

F=107.6nN

B. Since the charges are both positive, the force is repulsive

A trash can slides on a level floor after being pushed by an unhappy student. It slows and comes to a stop with a constant accel
castortr0y [4]

Answer:

Explanation:

Given:

Acceleration, a = -2.4 m/s^2

Acceleration due to gravity, g = 9.8 m/s^2

Sum of forces = 0

Fr + F = 0

Fr = µsl × m × g

Since, Fn = m × g

m × a = (- µsl × mg)

µsl = -a/g

= 2.4/9.8

= 0.245
