Answer:
3.76188 kg
36.9040428 N
Yes
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
L = Length of rod = 81.2 cm
d = Diameter of rod = 2.75 cm
r = Radius =
A = Area of the cylinder =
v = Volume =
m = Mass
= Density of rod = 7800 kg/m³
Density
The mass of the rod is 3.76188 kg.
As the the mass of the rod is 3.76188 kg I will be able to carry the rod.
Weight
The weight of the rod is 36.9040428 N
Answer:
The current flows through the insulator is 2 mA.
Explanation:
Given that,
Resistance
Voltage = 200 kV
We need to calculate the current
Using ohm's law
Where, I = current
V = voltage
R = resistance
Put the value into the formula
Hence, The current flows through the insulator is 2 mA.
Answer:
magnetic field will allow the electron to go through 2 x T k
Explanation:
Given data in question
velocity = 5.0 ×
electric filed =
To find out
what magnetic field will allow the electron to go through, undeflected
solution
we know if electron move without deflection i.e. net force is zero on electron and we can say both electric and magnetic force equal in magnitude and opposite in directions
so we can also say
F(net) = Fe + Fb i.e. = 0
q V B + q E = 0
q will be cancel out
+ 5e + 7i × B = 0
B = 2 x T k
