Explanation:
An electric current produces a magnetic field when the current flows through a wire. The correct answer will be A.
Answer:
The centripetal force on the boy = 2.888 N
Explanation:
Given:
m = 30 kg
r = 1.5 m
v = 0.38 m/s
To Find:
The centripetal force on the boy = ?
Solution:
F = m x v^2 / r
F = 30 kg x (0.38 m/s)^2 / 1.5 m
F = 30 x 0.1444 / 1.5
F = 2.888 N
Therefore,
The centripetal force on the boy = 2.888 N
