In which case F=G ( question from force )please as soon as possible​

atomic = no of protons.

mass number-atomic number = neutron number

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

its a 5.5 n

glad that

it would be c. predictability
