Answer:
The spring scale reads
Explanation:
From the question we are told that
The first force is
The acceleration by which the cart moves to the right is
The mass of the cart is m = 3.231 kg
Generally the net force on the cart is
This net force is mathematically represented as
So
Formula of the gravitational force between two particles:
where
is the gravitational constant
m1 and m2 are the masses of the two particles
r is their distance
(a) particle A
The gravitational force exerted by particle B on particle A is
to the right
The gravitational force exerted by particle C on particle A is
to the right
So the net gravitational force on particle A is
to the right
(b) Particle B
The gravitational force exerted by particle A on particle B is
to the left
The gravitational force exerted by particle C on particle B is
to the right
So the net gravitational force on particle B is
to the right
(c) Particle C
The gravitational force exerted by particle A on particle C is
to the left
The gravitational force exerted by particle B on particle C is
to the left
So the net gravitational force on particle C is
to the left
