A) \[\text{12 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{3}}}\text{J}\]
B) \[\text{10 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{3}}}\text{J}\]
C) \[\text{6 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{3}}}\text{J}\]
D) \[\text{3 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{3}}}\text{J}\]
Correct Answer: A
Solution :
Heat produced by heater is given by \[H=Pt\] Given,\[p=100W,\,t=2\min =2\times 60\,s=120\,s\] \[\therefore \] \[H=100\times 120=12\times {{10}^{3}}\,J.\]
