A3500-kg statue is placed on top of a cylindrical concrete (y = 2.3 times 10^10 n/m^2) stand. the stand has a cross-sectional area of 7.3 times 10^-2 m^2 and a height of 1.8m. by how much the statue compress the stand?

The statue compress the stand by 3.68 x 10⁻⁵ m.

Explanation:

Change in length

Load, P = 3500 x 9.81 = 34335 N

Young's modulus, Y = 2.3 x 10¹⁰ N/m²

Area, A = 7.3 x 10⁻² m²

Length, L = 1.8 m

Substituting

The statue compress the stand by 3.68 x 10⁻⁵ m.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
