in this problem, we have given a 50 KT. Man stands on a scale that measures force in an elevator, traveling up with an acceleration of G by four. So this is elevator. It is moving with acceleration in a forward direction. It is a cold G four. So we know that. I suppose this is men and we know that normal force, the skill will read the normal force. And we know that M G force will be in the downward direction. So when a lot. But it is moving in the right direction. We can write and yeah, minus mg should be cool too. I am into a so the normal force will be called, um G plus A. Or we can write. It is equal to mass, which is 50 kg into G plan Z by four, which is five g by four. So normal force will be equal to 5. 15 to 5. I don't if we take G is equal to 10. So this is 10 by four. This is equal to 25 five. This is 6 25 new can. So the scale will read a force equal to 6 25 Newton Now we will check the oceans. So Option B is correct. Yeah. Yeah. And it is Answer for this question. Thank you.
