c. 2341.53 Hz , 3053.34 Hz
Explanation:
a. smallest use the capacitive 4.2 uF + 6.0 uF = 10.2uF replacing:
b. second smallest use the capacitive 6 uF so:
c. second largest and largest oscillation first combination so:
Use 4.2 uF
And finally largest oscillation cap in serie so:
Answer:
A) 2.89 × 105 N/C, radially inward
Explanation:
The magnitude of the electric field generated by a charged sphere is given by the following formula:
( 1 )
k: Coulomb's constant = 8.98*10^9 Nm^2/C^2
Q: charge of the sphere = -6.50*10^-6 C
r: distance from the center of the sphere to the point in which E is calculated
r = 0.150m + 0.300m = 0.450 m
You replace the values of Q and r in the equation (1):
The electric field points radially inward because the charge is negative.
hence, the answer is:
A) 2.89 × 105 N/C, radially inward
