Answer:
Explanation:
We know that the electric force equation is:
- k is the electric constant
- r is the distance between the particles
- q1 and q2 are the particle
Now, we have three particles, the first one at x=0, the second one at x=2a and the third in some place between these two particle.
1. Let's find the electric force between the first particle and the third particle.
r(31) is the distance between 3 and 1
2. Now, let's find the electric force between the third particle and the second particle.
r(32) is the distance between 3 and 2.
Now, or
The net force must be zero so:
We just need to solve it for r(31)
Therefore the distance from the origin will be:

Answer:
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
For the boat in the problem,
v = 10 m/s
u = 0
t = 2 s
Substituting, we find the acceleration
