A Long slender bar having uniform rectangular cross- action \['B\times H'\] is acted upon by an axial compressive force. The sides B and H are paralled to x-and y-axes respectively. The ends of the bar are fixed such that they behave as pinpointed when the bar buckles in a plane normal to x-axis, and they behave as built-in when the bar buckles in a plane normal to y-axis. If load capacity in either mode of buckling is same, then the value of \[\frac{H}{B}\] will be B:

1.	A Long slender bar having uniform rectangular cross- action \['B\times H'\] is acted upon by an axial compressive force. The sides B and H are paralled to x-and y-axes respectively. The ends of the bar are fixed such that they behave as pinpointed when the bar buckles in a plane normal to x-axis, and they behave as built-in when the bar buckles in a plane normal to y-axis. If load capacity in either mode of buckling is same, then the value of \[\frac{H}{B}\] will be B:
A.	2
B.	4
C.	8
