The final velocity is +15.0 m/s
Explanation:
The motion of the cart is a uniformly accelerated motion (=at constant acceleration), therefore we can use the following suvat equation:
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
t is the time
For the cart in this problem, we have:
u = +3.0 m/s (initial velocity)
(acceleration)
t = 8.0 s (time)
Substituting, we find the final velocity:

By applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.
<h3>Distance between q₂ and q₃</h3>The distance between the second charge and the third charge is given as;
r = 0.3 m
<h3>Force on q₂ due to q₃</h3>The net force on particle q₁ is determined by summing the individual forces together;
F(net) = F₁ + F₂
F(net) = -14.4 + 4.54
F(net) = -9.86 N
Thus, by applying Coulomb's law between the charges, the net force on the charged particle q₁ due to particle q₂ and q₃ is -9.86 N.
