The cork is positively charged, therefore we know tat there must be excess of positively charged protons present.
The charge 
of a proton is
;
therefore, the number 
that makes up a charge of 
is
which is the 3rd choice.
Force is calculated with the formula, F (force) = mass * acceleration.The unit N (Newton) is also known as kilogram-meter/seconds2.
So, F= 1300 kg * 1.07 m/s2 = 1391 N.
The answer is 1391 N.
An isotope of an element contains the same number of protons as the original element however, the number of neutrons depends on the different isotopes of the element.
