7. Which of the following statements are true statements about electric force? Choose all that apply.
a. Electric force is a contact force.
b. A doubling of the quantity of charge on one of the objects results in a doubling of the electric
force.
C. Electric forces between two charged objects increases with increasing quantity of charge on
the objects.
d. Electric forces can only act between charged objects - either like-charged or oppositely-
charged.
e. If object A attracts object B with an electric force, then the attractive force must be mutual -
i. e., object B also attracts object A with the same force.
f. Electric forces between two charged objects increases with increasing separation distance.

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)
