Answer:
4.2 x 10⁷N
Explanation:
Given parameters:
Charge on ball:
q₁ = 3C
q₂ = 14C
Distance between balls = 9000m
Unknown:
Force acting on the two balls
Solution:
The force experienced by the two charges is given by coulombs law. It is mathematically expressed as;
F = 
where k = 9 x 10⁹Nm²/C²
q is the charges
r is the distance
Input the variables and solve;
F = 
= 4.2 x 10⁷N
Upward and downward forces cancel out. Net force is 8 newtons to the right
A particle smaller than an atom or a <span>cluster of such particles </span>
Answer:
To find the acceleration of the object we have to apply Newton second law of motion that is F = mass × acceleration.
Explanation:
Given ,
F = 130N
M = 24kg
A = ?
F = m× a
then ,
130N = 24kg ×a
a = 130/24 = 5 m/s.
Answer:
Explanation:
The period of the simple pendulum is:
Where:
- Cord length, in m.
- Gravity constant, in 
.
Given that the same pendulum is test on each planet, the following relation is formed:
The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:
