To get the charge along the inner cylinder, we use Gauss Law
E = d R1/2εo
For the outer cylinder the charge can be calculated using
E = d R2^2/2εoR1
where d is the charge density
Use these two equations to get the charge in between the cylinders and the capacitance between them.
Answer
given,
Tension of string is F
velocity is increased and the radius is not changed.
the string makes two complete revolutions every second
consider the centrifugal force acting on the stone
=
now centrifugal force is balanced by tension
T =
From the above expression we can clearly see that tension is directly proportional to velocity and inversely proportional to radius.
When radius is not changing velocity is increasing means tension will also increase in the string.
Inertia is the property of all matter by which it tends to remain
in constant, uniform motion unless acted on by external force.
Answer:
464.69 m
Explanation:
First car

Second car
Distance = Speed × Time

Here, the time taken and the distance traveled will be the same
Equating the two equations

So, the first would have to move
in order to overtake the second car.
