The magnitudes of forces at F₁ and F₂ are :
F₁ = 3924 N
F₂ = 4120.2 N
We know that force is the amount of strength required to move a body. The magnitude of force is the sum of all the strengths applied on the body which is exerted by each force together on a particular body.
Given,
Length of plank = 2 m
Force on one end = F₁
Force on the other end = F₂
F₂ is applied to a point which is 0.5 m from the other end
Mass of plank = 20 kg.
Now let us calculate the magnitudes of the forces applied:-
1) Balance of angular momentum around the end where F₁ is applied.
F₂ × 0.5m - F₁ × 0 = mass × g × 1m
⇒ F₂ × 0.5 m= 20 kg × 9.81 m/s² × 1 m = 1,962 N×m
F₂ = 196.2 Nm / 0.5m = 3,924 N
2) Balance of forces
F₁ - F₂ = mg
F₁ = F₂ + mg = 3,924N + 20kg (9.81 m/s²) = 4,120.2 N
Therefore the magnitude of force F₁ is 3924 N and of force F₂ is 4120.2 N.

Answer:
Here u go :)
Explanation:
The more the speed is, the more braking distance it will need.
Hope it helps.
Answer:
0.214 m
Explanation:
In order for the bag to levitate and not fall down, the electrostatic force between the bag and the balloon must balance the weight of the bag.
Therefore, we can write:
where
k is the Coulomb constant
is the charge on the balloon
is the charge on the bag
r is the separation betwen the bag and the balloon
is the mass of the bag
is the acceleration due to gravity
Solving for r, we find the distance at which the bag must be held:
Answer.
Charged spheres attract each other when: They are oppositely charged
Explanation
Like charges do not attract to one another, rather they repeal. However, recent research in physics and mathematics has shown the opposite in that at particular distances two spheres that have similar charge can possibly attract each other. Using the method of image technique to solve this problem, equal charges may attract only possible if the force of gravity between the two charged bodies is way more than the electrostatic force of repulsion. This is to mean that equal charged spheres may attract if charge by mass ratio of the bodies charged is tending to zero.
