Question A block of mass \( 4 \mathrm{~kg} \) is kept on ground. The coefficient of friction between the block and the ground is 0.80 . An external force of magnitude \( 30 \mathrm{~N} \) is applied parallel to the ground. The resultant force exerted by the ground on the block is:
(A) 40 N
(B) 30 N
(C) 0 N
(D) 50 N📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
