Answer:

A net torque applied to an object causes the angular velocity of the object to change.

Explanation:

The rotational equivalence of force is called a Torque. Thus, a net torque will make an object to rotate with an angular acceleration. Due tothe fact that all rotational motions have an axis of rotation, then a torque must be defined about a rotational axis. A force applied to a point on an object about the axis of rotation is known as a torque.

Near the surface of Earth, an electric field points radially downward and has a magnitude of approximately 100 N/C. 1) What char
scoundrel [369]

Answer:

-2.50\times10^{-4} \text{ C} or -0.000250 C

Explanation:

The field points downward, which is the direction of a positive charge. In order for the penny to rise, it has to have a negative charge since its direction is opposite that of the field.

To calculate the magnitude of the charge:

The penny is to accelerate upward so it must overcome gravity. Hence, the net force to cause it to accelerate it upward is the difference between the electrostatic force and its weight.

F_N = F_E - W

F_E = F_N + W

F_E = ma + mg

F_E = m(a + g)

F_E = 0.0025(0.19+9.8)

F_E = 0.0025\times9.99

Now, the electric field intensity is given by

F_E = E \times q

where q = charge

q=\dfrac{F_E}{E}

q=\dfrac{0.0025\times9.99}{100}=0.00024975= 0.000250 to 3 significant figures.

In standard form, q = -2.50\times10^{-4} \text{ C} The negative sign indicates it has a negative charge, as explained initially.
