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* g`

w= weight of an object

m= mass of object

g= gravity =
`9.8 ms^(-2)`

`w=8kg* 9.8ms^(-2)=78.4kgms^(-2)=78Newton`

`(1kgms^(-2)=1N)`
