Answer:
Where m is Ashley's mass and M is Miranda mass, in kg.
Explanation:
Let m be Ashley's mass and M be Miranda mass, in kg.
By the law of momentum conservation, after the hop on, we have the following momentum equation:
mv + MV = (m + M)S
where v = 3m/s is Ashley speed before the hop on, V = 4.2 m/s is Miranda's speed before the hop on. And S is their speed after
The magnitude and direction of the force on the charge is -12 N opposite the electric field
To calculate the force on a charge in an electric field, we make use of the formula below.
<u>Formula</u>
F = E×Q .......................... Equation 1
Where:
- F = Force on the charge
- E = Electric Field
- Q = charge
From the question,
Given:
Substitute these values into equation 1
Note: The negative sign indicates that the force is in the direction negative of the electric field.
Hence, The magnitude and direction of the force on the charge is -12 N opposite the electric field
