Question:
A man weighs 80 kg, he stands on a weighing scale in a lift which is moving upwards with a uniform acceleration of 5 m/s2. What would be the reading on the scale? (g=10 m/s2)

- Zero
- 400 N
- 800 N
- 1200 N
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Reading of weighing scale
= m(g+a)
= 80 (10+5)
= 80 x 15
= 1200 N
So, the correct option is (D): 1200 N

- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
