A wire of length L, mass m and carrying ...

A wire of length L, mass m and carrying a current I is suspended from point O as shown, An another infinitely long wire carrying the same current I is at a distance L below the lower end of the wire. Given i=2A, L=1m and m=0.1kg (In 2=0.693)

What is the angular acceleration of the wire just after it is released from the position shown ?

A

`6.2xx10^(-8)(rd)/(s^(2))`

B
