Desde un helicóptero se muestra dos personas tirando de una terca mula. La persona de la derecha tira con una fuerza F1 de magnitud 120 N y dirección de
01= 60.0 °. La persona de la izquierda tira con una fuerza F2 de magnitud 80.0
Ny dirección de 02 = 75.0°. Encuentra (a) la fuerza resultante de las dos fuerzas
mostradas y (b) la fuerza que una tercera persona tendría que ejercer sobre la
mula para hacer la fuerza resultante igual a cero. No olvidar la dirección de la
fuerza

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
