MCQ Questions

Four objects are situated in places with different gravitational field strengths. Which object has the greatest weight?

Mass(KG), Gravitational Field Strength(N/KG)
A 3.0, 10.4
B 3.5, 9.5
C 4.0, 10.2
D 4.5, 9.0

Choose the correct answer

please also tell the formula you used and also the procedure you used to get the answer.

Answer 1

The answer is -

(C) 4.0, 10.2

Because in scientific language weight = force , acceleration = G(Gravitational Field Strength)

Therefore,

         F(force) = m(mass) x a(value of 'G' )

                       =4.0 x 10.2

                       = 40.8

 : . 40.8 is the highest answer in the given options.

Answer 2

we know weight is the force by which a object is attracted by earth.

here,there are diffrent gravitational field strengths which are equal to N/Kg.

so to find the weight i.e force (in newton) we need to multiply N/Kg by Kg i.e gravitational field strength(N/Kg) by mass(Kg).

therefore the correct answer will be
C)
$4 \times 10.2$
