જો ઝડપ \(V\) , ક્ષેત્રફળ \(A\) અને બળ \(F\) ને મૂળભૂત રાશિ લેવામાં આવે તો યંગ મોડ્યુલસનું પરિમાણ શું થશે?

  1. A \(FA ^{-1} V ^{0}\)
  2. B \(FA ^{2} V ^{-1}\)
  3. C \(FA ^{2} V ^{-3}\)
  4. D \(FA ^{2} V ^{-2}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(FA ^{-1} V ^{0}\)

Step-by-step Solution

Detailed explanation

\(Y = F ^{ x } A ^{ y } V ^{z}\) \(M ^{1} L ^{-1} T ^{-2}=\left[ MLT ^{-2}\right] x \left[ L ^{2}\right] y \left[ L T ^{-1}\right]^{z}\) \(M ^{1} L ^{1} T ^{-2}=[ M ]^{ x }[ L ]^{ x +2 y +z}[ T ]^{-2 x - z }\) comparing power of \(ML\) and \(T\) \(x=1 \ldots(1)\)…
