A) 4 m
B) 5 m
C) 6 m
D) 7 m
Correct Answer: A
Solution :
We know that in this case acceleration of falling magnet will be lesser than g. If g would have been acceleration, then distance covered \[= \,\frac{1}{2}\,g{{t}^{2}}= 5 m.\] Now the distance covered will be less than 5 m. Hence only option [a] is correct.You need to login to perform this action.
