Explanation:
The answer is D if im correct
Answer:
The gravitational force is much larger than the electrical force for any distance between the particles.
Explanation:
The forces on the y axis are:
N-mgcos(60)=0 , wich becomes
N=mgcos(60)
Rember that the friction force is always contrary to the motion of an object and its formula is f=μ * N
The forces in the x axis are:
-f + mgsin(60)= m * a
-μ*mgcos(60) + mgsin(60)=m*a ,
μ = ( m*a - mgf=μ[sin(60) )/ ( mgcos(90) )
Its “A“ primary waves!!!!!!
