2. Three charged particles are placed at the corners of an equilateral triangle of side 1.20 m. The charges are +7.0μC, -8.0 μC

Scorpion4ik [409]

Answer:

0.53 N, 25.6°

Explanation:

side of triangle, a = 1.2 m

q = 7 μC

q1 = - 8 μC

q2 = - 6 μC

Let F1 be the force between q and q1

By using the coulomb's law

$F_{1}=\frac{Kq_{1}q}{a^{2}}$

$F_{1}=\frac{9\times 10^{9}\times 7\times 10^{-6}\times 8\times 10^{-6}}{1.2^{2}}$

F1 = 0.35 N

Let F2 be the force between q and q2

By using the coulomb's law

$F_{2}=\frac{Kq_{2}q}{a^{2}}$

$F_{2}=\frac{9\times 10^{9}\times 7\times 10^{-6}\times 6\times 10^{-6}}{1.2^{2}}$

F2 = 0.26 N

Write the forces in the vector form

$\overrightarrow{F_{1}}=0.35\widehat{i}$

$\overrightarrow{F_{2}}=0.26\left ( Cos60 \widehat{i}+Sin60\widehat{j}\right )$

$\overrightarrow{F_{2}}=0.13 \widehat{i}+0.23\widehat{j}$

Net force

$\overrightarrow{F}=\overrightarrow{F_{1}}+\overrightarrow{F_{2}}$

$\overrightarrow{F}=0.48 \widehat{i}+0.23\widehat{j}$

Magnitude of the force

$F=\sqrt{0.48^{2}+0.23^{2}}$

F = 0.53 N

Direction of force with x axis

$tan\theta =\frac{0.23}{0.48}$

θ = 25.6°

Instead of rolling down the ramp over the step, imagine the ball falls off the back of the ramp directly to the ground. What is

lesya692 [45]

According to the law of conservation of energy, the potential energy is converted to kinetic energy. Remember, potential energy is calculated using height and weight. If the ball is on the ground, height is 0.
