YesvI think the same

Class : Class 10
yeah

Yeah bro

YOu are absolutely right dude

Hi friend. The ans is (A) 100 because on richter scale the magnitude is increased ten times every number. for example 2 is 10 times 1 on richter scale.

In my opinion, the answer should be option (A) instead of option (B). On the Richter scale (which is a non-linear scale), the power of an earthquake increases by 10 with every consequent number. Thus, an earthquake of 2 on the Richter scale is 10 times more powerful than an earthquake of 1 on the Richter scale. Thus, an earthquake of 8 on the Richter scale is more powerful than an earthquake of 6 on the Richter scale, by a factor of 10⁸⁻⁶, or 10². Thus, an earthquake of 8 on the Richter scale is 100 times more powerful than an earthquake of 6 on the Richter scale.
