Which statement most completely describes gravity and does not contain any errors? Gravity is an acceleration of about 10 m/s/s that acts downward on a freefalling object. Gravity is an acceleration of about 10 m/s/s that acts downward on a freefalling object. Gravity is an acceleration of about 10 m/s/s that always acts downward on a freefalling object as it travels both upward and downward and while it is stopped at the top. Gravity is an acceleration of about 10 m/s/s that always acts downward on a freefalling object as it travels both upward and downward and while it is stopped at the top. Gravity is an acceleration of about 10 m/s/s that acts downward on a freefalling object as it travels both upward and downward.

The correct option is "Gravity is an acceleration of about 10 m/s/s that acts downward on a freefalling object"

Explanation:

Gravity can be described as a force of attraction between two bodies or a force that planetary bodies use to pull objects towards themselves. The latter description is the one been tested in the question.

The acceleration due to gravity on earth is 9 m/s² which is the same as 9 m/s/s. Because gravity is a force of attraction, hence it can only be said to act downward on a free-falling object and NOT upwards (as that would no longer be attraction but repulsion).

tube or goog with be a great resource to with that question

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
