Answer:
Explanation:
Electrical energy is the correct answer
Answer:
(a) Electrostatic force F=4.51×10⁻¹⁷N
(b) Number of electron n=4425 electrons
Explanation:
Given data
Charges q₁=q₂= -7.08×10⁻¹⁶C
Distance r=1.00cm =0.01 m
To find
(a) Electrostatic force F
(b) Number of electron n
Solution
For (a) Electrostatic force
From Coulombs law we know that
For (b) number of electron n
The number of electron on the drop that giving it its imbalance is the total charge divided by charge of electron
As we now that charge of electron e= -1.6×10⁻¹⁹C
Answer:
8.475 x 10^7 Pa
Explanation:
h = 8648 m, g = 9.8 m/s^2, density of water, d = 1000 kg/m^3
Pressure at a depth is defined as the product of depth of water , acceleration due to gravity and density of water.
P = h x d x g
P = 8648 x 1000 x 9.8 = 8.475 x 10^7 Pa
