Answer:
or .
Explanation:
<u>Given:</u>
- Charge on the particle at origin = Q.
- Mass of the moving charged particle,
- Charge on the moving charged particle,
- Distance of the moving charged particle from first at t = 0 time,
- Speed of the moving particle,
For the moving particle to circular motion, the electrostatic force between the two must be balanced by the centripetal force on the moving particle.
The electrostatic force on the moving particle due to the charge Q at origin is given by Coulomb's law as:
where, is the Coulomb's constant having value
The centripetal force on the moving particle due to particle at origin is given as:
For the two forces to be balanced,
The Inertia is 22. 488 kg. m² and the speed just before it hits the ground is 6. 4 m/s

How to determine the inertia</h3>
Using the formula:
I = 1/2 M₁R₁² + 1/2 M₂R₂²
Where I = Inertia
I = 1/2 * 0.810* (2. 60)² + 1/2 * 1. 58 * (5)²
I = 1/2 * 5. 476 + 1/2 * 39. 5
I = 2. 738 + 19. 75
I = 22. 488 kg. m²
To determine the block's speed, use the formula
v =
v =
v =
v = 6. 4 m/s
Therefore, the Inertia is 22. 488 kg. m² and the speed just before it hits the ground is 6. 4 m/s

Answer:
Reflected line
Explanation:
The angle between the reflected ray and the normal ray is called angle of reflection.
Answer:
187.38 m
Explanation:
Using the equation of motion
s = ut + 1/2gt²...................... Equation 1
Where s = distance of fall, u = initial velocity of the rock, t = time taken for the rock to fall from rest, g = acceleration due to gravity of venus.
Given: u = 0 m/s ( from rest), t = 6.5 s, g = 8.87 m/s².
substituting into equation 1
s = 0(6.5) + 1/2(8.87)(6.5)²
s = 0 + 374.7575/2
s = 187.38 m.
Hence the rock will fall 187.38 m
