A magnet is cut in three equal parts by cutting it perpendicular to its length. The time period of original magnet is `T_0` in a uniform magnetic field B. Then, the time period of each part in the same magnetic field is

Options

A. `(T_(0))/(2)`
B. `(T_(0))/(3)`
C. `(T_(0))/(4)`
D. None of these

Answer

b

Explanation

In the case of vertical cutting
`T_(1)=("Original time period")/(n)`
`T_(1)=(T_(0))/(3)`.
