Question

if speed(v) acceleration and force are considered as fundamental units the dimension of young modules will be???

Answer 1

Answer:

V^-4 A ^2 F (option 3 )

Explanation:

F/A = y Δl/l

[y] = F/A

F = ML / T^2

L^2 = F^2 /M^2 (V/A)^4

T= V/A

L^2 = F^2 / M^2 A^2 * V^4 / A^2 F = MA

L^2 = V^4 /A^2

[Y]= F/A = F V^-4 A^2
