Answer:
the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
Explanation:
As we know that the gravitational force on electron at y = 0 is counter-balanced by the weight of the electron
So we have
here we have
also we know that
so we will have
so the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
Answer:
The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight is approximately 19.81 m/s
Explanation:
The given parameters are;
The curvature of the hill, r = 200 m
Due to the velocity, v, the occupants weight = 20% less than the normal weight
The outward force of an object due to centripetal (motion) force is given by the following equation;
Where;
r = The radius of curvature of the hill = 200 m
Given that the weight of the occupants, W = m × g, we have;
v = √(0.2 × g × r)
By substitution, we have;
v = √(0.2 × 9.81 × 200) ≈ 19.81
The velocity of motion at which the occupants of the car appear to weigh 20% less than their normal weight ≈ 19.81 m/s.
Let's see
Now we know the formula of acceleration
