Physics - Kinematics Question with Solution | TestHub
A block A is placed on wedge B, which is placed on horizontal surface. All the contact surfaces are rough but friction is not sufficient to prevent sliding at any surface. Match Column I and II. Column II indicates possible direction(s) of the physical quantities mentioned under Column I. X and Y axes are along the incline and perpendicular to the incline
Column-I | Column-II |
|---|---|
(A) Acceleration of A | (P) |
(B) Net force applied by A on B | (Q) |
(C) Acceleration of A relative to B | (R) |
(D) Net force applied by ground on B | (S) |
Options:
Answer:
Solution:
(A) The net acceleration of A is the vector sum of and . It may be along q or r.
(B) The net force applied by A on B will be the vector sum of and . It may be along q or r.
(C) The acceleration of A relative to B is along P.
(D) The net force applied by the ground on B is along S, which is the vector sum of the ground friction and normal reaction.
