Answer:
F = 2.40 ×
N
Explanation:
given data
charge q1 = 3.95 nC
x= 0.198 m
charge q2 = 4.96 nC
x= -0.297 m
solution
force on a point charge kept in electric field F = E × q ................1
here E is the magnitude of electric field and q is the magnitude of charge
and
first we will get here electric field at origin
So net field at origin is
E = (Kq2÷r2²) - (kq1÷r1²) ...............2
put here value
E = 9[(4.96÷0.297²)-(3.95÷0.198²)]
E = 400.72 N/C ( negative x direction )
so that force will be
F = 6 ×
× 400.72
F = 2.40 ×
N
F~1/r²
doubling the distance r, Decreases the force by ¼
Answer:
63 miles per hour
Explanation:
you just divide miles and hours to get your average speed
As waves get closer to the beach they increase in energy
