Walking on Ice


Assertion (A): Walking on horizontal slippery ice can be much more tiring than walking on ordinary pavement.
Reason (R): Walking on ice requires small steps to prevent slipping.
 
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Solution:

Assertion (A) is true due to low friction on ice. Reason (R) is also true as small steps are needed to minimize horizontal forces and prevent slipping. (R) explains why extra effort and carefulness are required, making the activity tiring.
