A small 16.8 g plastic ball is suspended by a 20 cm long string in a 103 N/C uniform electric field directed at 45o with respect to the horizontal. If the ball is in equilibrium when the string makes a 20.0° angle with the vertical, what is the net charge on the ball?
3. The figure shows a 2.0 g ball that holds a +25 nC charge hanging in an electric field E-200,000 N/C that points to the right. What is the angle θ ? 3. The figure shows a 2.0 g ball that holds a +25 nC charge hanging in an electric field E-200,000 N/C that points to the right. What is the angle θ ?
A –3.0 nC charge (on the left) and a +3.0 nC charge (on the right) are separated by some horizontal distance. The point P is a distance 5.0 mm away from each charge. The line from the negative charge (on the left) to point P makes a +25º angle with with the horizontal line between the two known charges. What is the magnitude of the net electric field at point P? (Hint: Make sure you can draw a diagram of...
a) Tetherball is a game that uses a ball hanging from a string attached to the top of a post, where the ball is sent flying around in the tangential direction. Assume a uniform gravitational acceleration g pointed downward. This is an example of what is known as a “conical pendulum.” i) Find the equilibrium angle that the string makes with the vertical for a given speed v such that the ball traces a circle at uniform height. ii) Estimate...
A small pith ball has charge of +1.50 mC and is tied to a massless string and placed in a 2d Electric Field. If the string has an angle of 30.0° with the vertical and the E field is given as E=2600.i-4850.j N/C, what is the mass of the ball in kg?
A 5.0 g charged ball is hanging from a thread in a uniform electric field. If the charge on the ball is 31 mC and the angle with the vertical made by the thread is 10°, what is the size of the electric field?
An isolated charged sphere with a mass of 15.0 g and charge 18 μC is suspended on a string in a uniform horizontal electric field of strength 1050 N/C directed to the right. Find the angle made by the string with respect to the vertical
A small 12.6 g plastic ball is tied to a very light 28.4 cm string that is attached to the vertical wall of a room. (See the figure (Figure 1).) A uniform horizontal electric field exists in this room. When the ball has been given an excess charge of -1.10μC , you observe that it remains suspended, with the string making an angle of 17.4° with the wall. Part A Find the magnitude of the electric field in the room. Part B Find the...
Please only round for the final answer A metal sphere hangs from a string and has 4 kg of mass. The sphere has a charge of +2.7 μC, A uniform electric field is turned on and directed to the righ (a) Which way does the sphere move? left right (b) What is the electric force on the metal sphere if the magnitude of the electric field is 10 N/C? (c) When the sphere reaches equilibrium, what is the angle that...
Question 3 of 3 A 0.0380 g positively charged ball with charge q = 4.15 μC is resting on a flat, frictionless, horizontal surface. For a time of t = 0.0380 s, a constant electric field of magnitude E = 795 N / C is directed vertical to the ball, which makes the ball rise to a height of d . After this time, the electric field is turned off, and the ball returns to the surface. Find the height...
