Transcribed Image Text:A charged particle of mass m
57.2 g and charge g = +2.14 uC is attached to a massless string of
Tength ? = 25.5 cm and spun in circular motion with w = 7.85 rad/s. Note that the circular motion
is about the rotational axis of the dotted ling and would trace out a conelike shape in three
dimensions. At the moment shown the charged particle is passing through an clectric field of
strength E that is angled above the horizontal direction at an angle of o - 18.3"
(a) If the angle the massless string makes with the vertical is 0 = 38,4° then what is the electrit
field strength E?
(b) What is the tension in the massless string?
(c) What would be the angle 0 if the centripetal force of the particle's circular motion was
ignored? What is the percent error between this value of 8 and 6= 38.4"?
(d) What would be the angle 0 if the particle's mass is ignored completely? What is the percent
error between this value of A and A = 38.4"?

- A strip of invisible tape 0.14 m long by 0.013 m wide is charged uniformly with a total net charge of 6 nC (nano = 1 ×10-⁹) and is suspended horizontally, so it lies along the x axis, with its center at the origin, as shown in the figure below. Calculate the approximate electric field at location m (location A) due to the strip of tape. Do this by dividing the strip into three equal sections, as shown in the figure below, and approximating each section as a point charge.
