Answer:

formula: work done = mgh

Explanation:

m=10 kg

g=10 m/s^2

h=10 m

Ans=> work done= 10*10*10

=1000 j

=1 kj

Work Done in lifting Weight of 10 kg at height of 10 m is 1kJ .

It can be calculated by using formula :

\huge{\boxed{\boxed{\sf{Work \: = \: mgh}}}}

  • m is mass
  • g is gravitational force
  • h is height

Substitute Values

\rightarrow {\sf{W \: = \: 10 \: \times \: 10 \: \times \: 10}} \\ \\ \rightarrow{\sf{W \: = \: 100 \: \times \: 10}} \\ \\ \rightarrow{\sf{W \: = \: 1000 \:J}} \\ \\ \rightarrow {\sf{W \: = \: \dfrac{1000}{1000}}} \\ \\ \rightarrow {\sf{W \: = \: 1 \: kJ}}
