You don't need both. GPE is the gravitational potential energy caused by the fact that an object is not touching the ground of the earth. KE is caused by an object moving. This problem says that the bowling ball "sits" meaning that you only need the GPE because it's not moving and it is not touching the surface. You would use the GPE equation to find how much Potential energy an object has. If you want its velocity, you would set the answer to the GPE equation equal to the KE equation to find its velocity.

An electron with a charge of -1.6 × 10-19 coulombs experiences a field of 1.4 × 105 newtons/coulomb. What is the magnitude of th

kipiarov [429]

Answer:

$2.24 \times 10^{-14}$ Newtons

Explanation:

Magnitude of charge on the electron = q = $1.6 \times 10^{-19}$ Coulombs

The negative sign in the question statement indicates that the charge is negative.

Magnitude of Electric Field experienced by the electron = E = $1.4 \times 10^{5}$ Newtons/Coulomb

Magnitude of Force on the electron = F = ?

The relation between the charge, electric field and the force on the charge because of electric field is given by:

$E=\frac{F}{q}$

From here we can write:

F = qE

Using the values, we get:

$F = 1.6 \times 10^{-19} \times 1.4 \times 10^{5}\\\\ F = 2.24 \times 10^{-14}$

Thus, the magnitude of the electric force experience by the electron would be $2.24 \times 10^{-14}$ Newtons

kumpel [21]

Answer:

Graph C

Explanation:

With the same force and more mass, the position in time will still be parabolic

i.e. x = ½at², but the rate of acceleration will be lower so the position curve will be broader.
