Below is an attachment containing the solution.
Answer:
no idea thanks you veryuch
The potential on the surface of the charged sphere is 3.9 × 10⁷ volts.
Given:
The diameter of the sphere is 2.30 m and the charge of 1.10 mc.
The potential on the surface of a charged sphere is given by,

Where V is the potential on the surface, Q is the charge, R is the radius and k is the Coulomb's constant.
V = 8.99×10⁹×5×10⁻³/(2.30÷2)
V = 3.9 × 10⁷ volts

Answer:
at load 13114.85 N beam fail
Explanation:
given data
radius r = 6.7 mm
load = 2710 N
distance = 41 mm
length = 19 mm
to find out
At what load we expect this specimen to fracture
solution
we will first flexural strength that is
flexural strength = load × distance / πr³
flexural strength = 2710 × 41 ×
/ π(6.7 ×
)³
flexural strength = 117.592 MPa
we know that for cross section specimen
flexural strength = 3load × distance / 2bd²
put here these value
117.592 ×
N/m² = 3 load × 41 ×
/ ( 2 × (19×
)³)
load = 117.592 ×
× ( 2 × (19×
)³) / ( 3 × 41 ×
)
load = 13114.85 N
so at load 13114.85 N beam fail
