Answer:
The electric field is 
Explanation:
Given that,
Radius = 0.357 m
Charge 
Point charge 
Distance = 0.815 m
We need to calculate the total electric field
Using formula of electric field
Where, q = point charge
r = distance
Put the value into the formula
Hence, The electric field is
In phase would mean both waves are at a positive peak, out of phase would mean one is at a positive whilst the other is at a negative. Out of phase would mean the waves cancel each other out
Answer:
I only know answer A and it's 2825.28 N/m, with rounding it's 2825.5
Explanation:
Use the m*g*h=1/2*k*x^2 equation
96*9.81*60=1/2*k*2^2
5650.56=2k
5650.56/2=2825.28N/m
