A hollow sphere of mass \[M=50kg\]and radius\[r={{\left( \frac{3}{40\pi } \right)}^{1/3}}\]m is immersed in a tank of water (density \[{{\rho }_{w}}={{10}^{3}}kg/{{m}^{3}}\]). The sphere is tied to the bottom of a tank by two wires A and B as shown. Tension in wire A is\[(g=10m/{{s}^{2}})\]

• A. \[125\sqrt{2}N\]
• B. \[125N\]
• C. \[250\sqrt{2}N\]
• D. \[250N\]
