Consider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false .
The normal force is not always parallel to the force of gravity
The normal force is independent of the force of gravity
The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity
The normal force causes an acceleration and therefore does not interact with gravity
Newton's universal law of gravitation states that every particle in the
universe attracts every other particle with a force along a line joining them.
The force is directly proportional to the product of their masses and
inversely proportional to the square of the distance between them.
Mathematically, it can be written as
GMm
F =
According to this law, when distance between two masses is reduced by half,
the force
becomes half compared to original
O becomes two times larger compared to original
becomes quarter of the original
becomes four times larger compared to original
Suppose an object is positioned at the origin. A force F, of magnitude 70 newtons (N) acts on the object at an angle of 193° with the positive x-axis. A force F,
of magnitude 30 N acts on the object at an angle of 309° with the positive x-axis. See the figure.

Explain.arrow_forwardA pendulum bob is attached to a string and allowed to swing. Which of the following statements is true with correct reasoning about the magnitude of the force the string exerts on the bob Fs on B and the magnitude of the force Earth exerts on the bob FE on B at the very bottom of the pendulum's swing? FS on B = FE on B because the bob is moving at a constant speed at that point so the forces exerted on it must be balanced. FS on B > FE on B because the string would not be able to support the bob if it were not. FS on B > FE on B because the bob is accelerating upward at the bottom of its swing.
