The force, F, acting on a charged object varies inversely to the square of its distance, r, from another charged object. When the two objects are 0.72 meters apart, the force acting on them is 6.4 Newtons. Approximately how

much force would the object feel if it is at a distance of 0.83 meters from the other object?

Help me !!!

Force will be approxmately 4.82 Newtons

Step-by-step explanation:

Step 1

letThe force, F, acting on a charged object which varies inversely to the square of its distance, r, from another charged be  given as

F ∝ I / r²

introducing the proportionality of constant,K we have

F ∝ I / r²

F =K I / r²

F= K/ r²

when the distance= 0.72, and force is 6.4 N, K will be

F= K/ r²

6.4N = K/ 0.72²

K= 6.4 X 0.72²

K=3.31776

step 2

when distance = 0.83, Force becomes

F= K/ r²

F= 3.31776/ 0.83²

F=4.82 Newtons

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
