A small 12.00g plastic ball is suspended by a string in a uniform, horizontal electric field with a magnitude of 10^3 N/C. If th
tensa zangetsu [6.8K]

Answer:

The net charge is 67.89 \mu C

Solution:

As per the question:

Mass of the plastic bag, m = 12.0 g = 12.0\times 10^{-3}\ kg

Magnitude of electric field, E = 10^{3}\ N/C

Angle made by the string, \theta = 30^{\circ}

Now,

To calculate the net charge, Q on the ball:

Vertical component of the tension in the string, T = Tcos\theta

Horizontal component of the tension in the string, T = Tsin\theta

Now,

Balancing the forces in the x-direction:

Tsin\theta = QE

Q = {Tsin\theta}{E}                             (1)

Balancing the forces in the y-direction:

Tcos\theta = mg

where

g = acceleration due to gravity = 9.8\ m/s^{2}

Thus

T = \frac{mg}{cos\theta }

T = \frac{12.0\times 10^{-3}\times 9.8}{cos30^{\circ}} = 0.1357\ N

Use T = 0.1357 N in eqn (1):

Q = {0.1357\times sin30^{\circ}}{10^{3}} = 6.789\times 10^{- 5}\ C

Q = 67.89\times 10^{- 5}\ C = 67.89\mu C

When a car drives over a speed bump and oscillates up and down in simple harmonic motion, at which position during the motion is
Oksana_A [137]
Using the second Law of Newton, F = m * a, you know that acceleration is maximum when the force is maximum.


Using Hooke's Law, F = K Δx, you know that the force is maximum when the displacement from the equilibrium (Δx) is maximum.


So the answer is that the acceleration is maximum at the maximum amplitude x = a.
