A wire is suspended from the ceiling and stretched under the action of weight F suspended from its other end. The force exerted by the ceiling on it is equal and opposite to the weight.A. Tensile stress at any cross-section `A` of the wire is `F//A`.B. Tensile stress at any cross-section is zeroC. Tensile stress at any cross-section `A` fo the wrie is `2F//A`D. Tension at any cross-section `A` fo the wire is `F`. |

Answer» Correct Answer - A::D Force at each cross-section is `F` Tension stress `= ("Force applied")/("Area of cross-section") = (F)/(A)` |
