The correct answer would be A. The forces are equal.
Answer:
Explanation:
Kinematic equation
v = u + at
If UP is assumed to be the positive direction and we let gravity be 10 m/s² which will be in the downward direction so will be negative.
a) v = 6 + (-10)(0.5) = 1 m/s the result is positive, so upward
b) v = 6 + (-10)(2) = -14 m/s the result is negative, so downward
Answer:
(a). I' = 17.24 A
(b).The current in second wire is in opposite direction compare to first wire.
Explanation:
Given data
r = 0.038 m
4.9 ×

I = 0.54 A
(a). The current in the second wire is calculated as

Put all the values in above formula we get

I' = 17.24 A
(b). The current in the two wires is in opposite directions because the wires repeal each other. therefore the current in second wire is in opposite direction compare to first wire.
