A rigid square loop of side 'a' and carrying current `I_(2)` is lying on a horizontal surface near a long current `I_(1)` carrying wire in the same plane as shown in figure. The net force on the loop to the wire will be :
A
Repulcive and equal to `(mu_(0)I_(1)I_(2))/(2pi)`
B
Attractive and equal to `(mu_(0)I_(1)I_(2))/(3pi)`
