Which one of newton's laws does a doll riding a dog represent

strojnjashka [21]

I believe it would best represent Newton’s first law; an object tends to stay at rest and an object tends to stay in motion unless acted upon by an unbalanced force. When the dog stops walking, the doll will continue to go forward because there is no unbalanced force acting in it.

What is the strength of the electric field 3.0 cm from a small glass bead that has been charged to + 8.0 nc ?

Debora [2.8K]

Thinking the small glass bead as a single point charge, the electric field generated by it is given by
$E(r) = k_e \frac{Q}{r^2}$
where
$k_e = 8.99 \cdot 10^9 N m^2 C^{-2}$ is the Coulomb's constant
$Q=8.0 nC=8.0 \cdot 10^{-9} C$ is the charge of the bead
$r=3.0 cm=0.03 m$ is the distance at which we calculate the field.

Using these data, we find:
$E=(8.99 \cdot 10^9 N m^2 C^{-2} ) \frac{(8.0 \cdot 10^{-9} C}{0.03 m)^2}=8.0 \cdot 10^4 N/C$
