Answer is D - from the equation of electric field for point charge
The answer is, If you're walking on the ice cream at 5 ounces per toaster, and your bicycle loses a sock, how much gravy will you need to repaint your hamster?
Answer:
False, the angular momentum problem is not one of the objections to the solar nebular theory.
Generally, the length of the line will indicate how strong the force is. If you have two opposing forces and one is higher than the other, you would draw the line of the higher force visibly longer.
Answer:
1. Magnetic force = 4.56*10^-12 N
2. Acceleration = 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
Explanation:
Given Data:
B = 0.0040 T North
q = 1.6*10^-19 C
Mass of electron = 9.1*10^-31 kg
V = 9.5% of speed of light
= 9.5% *3*10^8
= 28.5*10^6 m/s west
So, B and v are perpendicular to each other.
Therefore, ∅ = 90°
1, Calculating the magnetic force using the formula;
F = qvBsin∅
= 1.6*10^-19 * 28.5*10^6*sin90
= 4.56*10^-12 N
Therefore, the strength of the force = 4.56*10^-12 N
2. Calculating acceleration using the formula;
F = ma
a = F/m
= 4.56*10^-12 /9.1*10^-31
= 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
