A particle of mass 73 g and charge 67 µC is released from rest when it is 47 cm from a second particle of charge −25 µC. Determi

Answer:

933.804423995 m/s²

Explanation:

$q_1$ = Charge on particle 1 = 67 µC

$q_2$ = Charge on particle 2 = -25 µC

r = Distance between the particles = 47 cm

k = Coulomb constant = $8.99\times 10^{9}\ Nm^2/C^2$

m = Mass of particle = 73 g

Electric force is given by

$F=\dfrac{kq_1q_2}{r^2}\\\Rightarrow F=\dfrac{8.99\times 10^{9}\times -25\times 10^{-6}\times 67\times 10^{-6}}{0.47^2}\\\Rightarrow F=-68.1677229516\ N$

The magnitude of force is 68.1677229516 N

Acceleration is given by

$a=\dfrac{F}{m}\\\Rightarrow a=\dfrac{68.1677229516}{0.073}\\\Rightarrow a=933.804423995\ m/s^2$

The acceleration is 933.804423995 m/s²

Look at the densities of the jovian planets given in figure 1. which of the following statements best describes the pattern of j

avanturin [10]

Given the densities of the jovian planets, the densities is just like random numbers, so the densities of the jovian planets have no concrete pattern due to its randomness. pattern can be either linear or geometric, where linear you see a common difference among data, while geometric you observed a common ratio
