Two forces one of 12N and another of 5N act on abody in such away that they makes an angel of 90 with each other, what is the re
1 answer:
Answer:
13 N
Explanation:
From the question,
If two forces act at right angle to each other, Their result force can be calculated using Pythagoras theorem.
R'² = R₁²+R₂²....................... Equation 1
Where R' = Resultant force, R₁ = First force, R₂ = Second force.
Given: R₁ = 12 N, R₂ = 5 N
Substitute these values into equation 1
R'² = 12²+5²
R'² = 144+25
R'² = 169
R' =
R' = 13 N.
Hence the resultant force is 13 N

Answer:
The radius of the sphere is 4.05 m
Explanation:
Given;
potential at surface, = 450 V
potential at radial distance, = 150
radial distance, l = 8.1 m
Apply Coulomb's law of electrostatic force;
Therefore, the radius of the sphere is 4.05 m
