Answer:
Explanation:
Objects moving in circular path would be have either centripetal or centrifugal force.The force is either to center or away from center. When the object is moving along the circular path the centripetal force is
Here m is mass, v is velocity and r is radius of circular path
The acceleration is given by:
The point of interest is lowest point on circle.The acceleration of plane at this position point up.The speed of plane from radial acceleration equation is:
Substitute 17 m/s² for a and 450m for r
So
Answer:
5.648 N/C
Explanation:
Given:
q₁ = 60 pC/m² = 60 × 10⁻¹² C/m²
q₂ = -80 pC/m² = - 80 × 10⁻¹² C/m²
Now,
Electric field is given as:
E =
ε₀ = Permittivity of Free Space
thus, due to charge q₁
E₁ =
or
E₁ = 3.389 N/C
and, due to charge q₂
E₂ =
or
E₂ = 4.519 N/C
Now,
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field =
or
The resultant electric field = 5.648 N/C
