Answer:
As we keep on increasing the radius the value of the gravitation force of attraction decreases and as we decrease the radius the gravitation force increases.
Explanation:
Like the coulombs law of electrostatics, the law of gravitation also depends inversely on the square of the value of r. Therefore, as we keep on increasing the value of r the value of the gravitation force decreases and as we decrease the value of the r the value of gravitation force increases.
Gravitation Force=
Coulombs's Law= 
The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.
The motorized toy boat moves at 8 m/s (u) at 4 s and at 8 m/s (v) at 8 s. We can calculate the acceleration (a) in that period using the following kinematic expression.
The object with a mass (m) of 2.0 kg experiences an acceleration of 0 m/s². We can calculate the net force (F) in that period using Newton's second law of motion.

Answer:
8.24 m/s
Explanation:
Given:
t = 2.10 s
v₀ᵧ = 0 m/s
vₓ = 22.2 cos(-68.2) m/s
aₓ = 0 m/s²
Find: v₀
In the x direction:
v = at + v₀
22.2 cos(-68.2) = (0) (2.10) + v₀ₓ
v₀ₓ = 8.24
v₀² = v₀ₓ² + v₀ᵧ²
v₀² = (8.24)² + (0)²
v₀ = 8.24 m/s
