Answer:
Fe = 25.67 N
Fg = 2.0734 x 10^-35 N
Explanation:
r = 3 x 10^-15 m
G = 6.67 x 10^-11 Nm^2/kg^2
Mp = 1.6726231 x 10^-27 kg
Qp = 1.6021 x 10^-19 C
K = 9 x 10^9 Nm^2/C^2
The formula for the electrical force between the two protons is given by
Fe = 25.67 N
The formula for the gravitational force between the two protons is given by
Fg = 2.0734 x 10^-35 N

Answer:
A
Explanation:
1. When the block moves across a table top, F(pulling) = - F(frictional).
Sum of this forces = 0, so the block moves with uniform speed.
2. When the block is pulled on top of the table covered with beads
F(pulling) > - F(frictional).
So, the sum of forces (∑F) is a number that is more than 0 and directed to the direction of movement.
So, a = ∑F / m is positive and constant. Speed is increasing because
v(t) = v(0)+at
a is constant and directed forward.
That means a is acceleration, and constant.
Velocity can change when there is a change in direction and speed.
