Answer:
0.0299 N
Explanation:
Applying,
F = Gmm'/r²................... Equation 1
Where F = gravitational force between the boulders, m = mass of the first boulder, m' = mass of the second boulder, r = distance between the boulders, G = Universal constant.
From the question,
Given: m = 7.5×10⁶ kg, m' = 9.2×10⁵ kg, r = 124 m
Constant: G = 6.67×10⁻¹¹ Nm²/kg²
Substitute these values into equation 1
F = (6.67×10⁻¹¹× 7.5×10⁶ × 9.2×10⁵ )/124²
F = (460.23)/15376
F = 0.0299 N
Answer: the electric field is equal to: E=0 for r<2 cm; E= -2.29*10^4/r^2 for 2cm<r<4cm; E=0 for 4cm<r<5 cm; E=5.26*10^4/r^2 for r>5 cm
the electric field in N/C units
Explanation: In order to find the electric field for all r values, we have to use the definition of electric field and Gaussian law.
In this sense, for r<2 cm as it is inside a conductor teh electric field is zero.
for 2cm< r< 4 cm we applied the field from a spherical charge distribution so by the Gaussian law we find the total charge inside the gaussian surface so
E.4π r^2= Q inside/ε0 = -2.55μC/ε0
Idem for other regions.
for 4 cm<r< 5 cm in the outsider conductor the E=0
Finally, for r>5 cm
E.4π r^2=Q inside/ε0=(8.40-2.55)μC/ε0
Answer:
299.4 MeV
Explanation:
For 40 Ar
Number of neutrons = 22
Number of protons= 18
Mass of each proton = 1.007277 amu
Mass of each neutron= 1.008665 amu
Total mass of protons= 18 × 1.007277 amu = 18.130986 amu
Total mass of neutrons = 22 × 1.008665 amu = 22.19063 amu
Total mass of protons and neutrons= 18.130986 + 22.19063 = 40.321616 amu
Mass defect = 40.321616 amu - 40 amu
Mass defect = 0.321616 amu
Since 931 is the conversion factor from amu to MeV
Binding energy = 0.321616 amu × 931 = 299.4 MeV
Binding energy = 299.4 MeV
