If the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.
<h3>What is momentum?</h3>The momentum of an object in motion is the product of mass and speed of the object.
P = mv
<h3>Conservation of linear momentum</h3>The principle of conservation of linear momentum states that, the sum of the initial momentum must be equal to the sum of the final momentum.
Thus, if the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

Answer:
q = 3.6 10⁵ C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth
r = 6 , 37 106 m
E = k q / r²
q = E r² / k
q =
q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius
r = 0.6 r_ Earth
r = 0.6 6.37 10⁶ = 3.822 10⁶ m
E = k q / r²
q = E r² / k
q =
q = 3.6 10⁵ C
