The moon keeps going around earth for billions of years but never falls down because O the moon's transverse (perpendicular to radius of orbit) speed keeps it from falling down O None of the other answers is correct O the law of gravity applies to objects on earth's surface, not to objects in the heavens O gravity from sun cancels the gravity from earth so there is no net force on the moon O the moon is so far away that the earth's gravity is too weak to make it fall down

Immediately after two charged particles located in each other's proximity are released from rest, they
both start accelerating (moving with increasing speed). This is possible,
O only if the two charges have the same sign
G
O either way, whether the two charges have the same sign or opposite sign
only if there is a non-electric force acting on the particles, because equal and opposite electric forces will
cancel each other
