Answer:
255.4 N/m
Explanation:
We can consider the system eyeball-attached to the musculature as a mass-spring system in simple harmonic motion, whose frequency of oscillation is given by
where in this case, we know:
f = 29 Hz is the frequency of oscillation
k is the spring constant, which is unknown
m = 7.7 g = 0.0077 kg is the mass of the eyeball
Solving the equation for k, we find the spring constant of the musculature attached to the eyeball:
Answer:
The number of excess electrons are on the negative surface is
Explanation:
Given that,
Distance =1.5 cm
Side = 22 cm
Electric field = 18000 N/C
We need to calculate the capacitance in the metal plates
Using formula of capacitance
Put the value into the formula
We need to calculate the potential
Using formula of potential
Put the value into the formula
We need to calculate the charge
Using formula of charge
Put the value into the formula
Here, the charge on both the positive and negative plates
We need to calculate the number of excess electrons are on the negative surface
Using formula of number of electrons
Put the value into the formula
Hence, The number of excess electrons are on the negative surface is
