A current carrying coil is placed in xy-plane as shown in figure. At this instant if angular acceleration of coil is $\frac{xIB _{0} π}{m}$ then find value of x .

Answer:

2.00

Solution:

Mass of coil $= m$

$τ = I α$

$(I π R^{2}) B_{0} = (\frac{m R ^{2}}{2}) α$

$α = \frac{2 I B _{0} π}{m}$

$x = 2$
