Calculate the force experienced by a positive test charge of 8.1 × 10-9 coulombs if the electric field strength is 9.4 × 107 newtons/coulomb.

Respuesta :

We can answer this problem by dimensional analysis. As we can see, the units of the electric field strength is newtons per coulomb. If we multiply a value with units of coulomb we will obtain newtons which is a units of force. 

Force = 9.4x10^7 N / C (8.1 x10^-9 C)
Force = 0.7614 N

Answer:

C. 7.6 x 10^-1 newtons #PLATOLIVESMATTER

Explanation:

Force = 9.4x10^7 N / C (8.1 x10^-9 C)

Force = 0.7614 N

Force = 7.6 x 10^-1 N
