Answer:

The spring scale
`F_2` reads
`F_2 = 2.4225 \ N`

Step-by-step explanation:

From the question we are told that

The first force is
`F_1 = 10.5 \ N`

The acceleration by which the cart moves to the right is
`a = 2.50 \ m/s^2`

The mass of the cart is m = 3.231 kg

Generally the net force on the cart is

`F_(net) = F_1 - F_2`

This net force is mathematically represented as

`F_(net) = m * a`

So

`m* a = 10 - F_2`

`F_2 = 10.5 - 2.5 (3.231)`

`F_2 = 2.4225 \ N`
