B after 2 Objects A and B are dropped
from rest. Object A has mass m
and object B has mass 2m. After
2 seconds of free fall, object A
has a speed v and has fallen a
distance d. What are the speed
and distance of fall of object B
after 2 seconds of free fall?
F speed =ž distance =
G speed = v. distance = d
H speed = i distance = 20
J speed = 2v: distance = 20

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
