Fnet=m*a
a= Fnet/m
a=(20N[E]+9.0N[E])/ 12.0kg
a=2.4167m/s^2
a ≈ 2.4m/s^2
Answer:
Energy moves between the particle of the medium.
Explanation:
Answer:
<h2>10 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 2 × 5
We have the final answer as
<h3>10 N</h3>
Hope this helps you
Answer:
Explanation:
Let the charge on bead A be q nC and the charge on bead B be 28nC - qnC
Force F between them
4.8\times10^{-4} = 
=120 x 10⁻⁸ = 9 x q(28 - q ) x 10⁻⁹
133.33 = 28q - q²
q²- 28q +133.33 = 0
It is a quadratic equation , which has two solution
q_A = 21.91 x 10⁻⁹C or q_B = 6.09 x 10⁻⁹ C
