The Earth's electric field creates a potential that increases 100 V for every meter of altitude. If an object of charge 4.5 mC a

Answer:

The final kinetic energy is $K = 1.1 \ J$

Explanation:

From the question we are told that

The electric field is $E = 100 \ V/m$

The charge on the object is $q = 4.5 mC = 4.5 *10^{-3} \ C$

The mass of the object is $m_o = 68 \ g = 0.68 \ kg$

The distance moved by the object is $d = 1.0 \ m$

The workdone on the object by the fields is mathematically represented as

$W = [qE + mg]d$

Now this workdone is equivalent to the final kinetic energy so

$K = W = [qE + mg]d$

substituting values

$K = W = [4.5*10^{-3 } *100 + 0.68 * 9.8]* 1$

$K = 1.1 \ J$
