Answer:
C. The block and the sphere would have the same weight.
Explanation:
If both the block and the sphere weigh 7 kilograms then they have the same weight. They may look different, but they both weigh 7 kilograms.
A- electric forces only - WHEN The force exerted on a stationary charged object is nonzero.
B- magnetic forces ONLY - The magnitude of the force depends on the charged object's direction of motion.
C- both electric and magnetic forces - The force is proportional to the magnitude of the charge of the object on which the force is exerted.
D- neither electric nor magnetic forces- The force exerted on a moving charged object is zero.
(vi)- The force exerted on a charged object is proportional to its speed- magnetic forces only

Sum up the moments of the right and the left support:
∑ M2 = 0
F1 · 3.92 m = 46 kg · 9,81 m/s² · 4.46 m + 250 kg · 9.81 m/s² · 1.96 m
F 1 · 3.92 = 2012.6 + 4806.9
F 1 = 6819.5 : 3.92
F 1 = 1739.67 N
∑ M 1 = 0
F 2 · 3.92 m + 46 kg · 9.81 m/s² · 0.54 m = 250 kg · 9.81 m/s² · 1.96 m
F 2 · 3.92 + 243.68 = 4806.9
F 2 · 3.92 = 4563.22
F 2 = 4563.22 : 3.92
F 2 = 1164 N
Answer: The forces on the beam are: F 1 = 1739.67 N and F 2 = 1164 N.
The center of an atom is called the nucleus.
