Question

A lamp has a mass of 8 kg. What is the weight of the lamp?

. 93 N
. 85 N
. 78 N
. 109 N
Which one please

Answer 1

78. g on earth is 9.8 m/s^2 so F=ma and plugging in gives you F=(8kg)(9.8m/s^2) which is closest to 78 N.

Answer 2

Answer:  78 N

Explanation: Weight is the downward force acting on an object due to gravity.

$w=m\times g$

w= weight of an object

m= mass of object

g= gravity = $9.8 ms^{-2}$

$w=8kg\times 9.8ms^{-2}=78.4kgms^{-2}=78Newton$

$(1kgms^{-2}=1N)$
