Answer:
Electric force,
Explanation:
Given that,
Charge 1,
Charge 2,
Distance between charges, d = 2 km
The electric force is given by :
k is the electrostatic constant
F = 1294207.2 N
or
Hence, this is the required solution.
Answer:
in simple harmonic motion, the formula for finding amplitude is:
a = -ω^2 x
where, a=amplitude, ω= angular frequency, x= Displacement
Explanation:
Answer:
Explanation:
The force of friction equals the sine component of the force due to gravity
