Consider two coils, with the first coil having twice as many loops as the second. Given the flux Φ though each loop of the first coil due to current in the second coil, what can be said about the flux through each loop of the second coil due to an equal current in the first coil?

Which means that the flux through each loop of the second coil is half as much as flux through each loop of first coil.

Explanation:

The flux through each loop of the first coil due to current in the second coil is,

The number of loops in the first coil is

no. of loops = 2N

Total flux passing through the first coil is

The flux through each loop of the second coil due to current in the first coil is,

The number of loops in the second coil is

no. of loops = N

Total flux passing through the second coil is

Comparing both

Which means that the flux through each loop of the second coil is half as much as flux through each loop of first coil.

it is a negative acceleration

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
