Two force of 126N and 215N act on an object,calculate the magnitude and direction

1 answer:

7 0

The magnitude of the net force could be anything from 89N to 341N , and it could be acting in ANY direction.

To solve both mysteries we need to know the directions of the original two forces.

Answer:

F= 67.5 N

Explanation:

We use the equation for the Coulomb's Law of Force between two charges Q1 and Q2 (in Coulombs) separated by a distance d (in meters):

$F=k\frac{Q1*Q2}{d^2}$

where the constant k is the Coulomb's constant ( $9*10^9 N\frac{m^2}{C^2}$

The charges are $Q1=3.0*10^{-6}C$ , Q2=2.5*10^{-7}C; the distance we convert into meters to match the appropriate units of the Coulomb constant k (1 cm = 0.01 m)
