Question

When two spheres of same radius are placed on H.P both are touching each other and the line joining the centers is perpendicular to V.P. The top view will be _______________

(a) single circle

(b) two circles

(c) concentric circles

(d) intersecting circles

This question was posed to me during an interview for a job.

This interesting question is from Projection of Spheres in portion Projection of Solids of Engineering Drawing

Answer 1

Correct choice is (b) two circles

Explanation: Given two spheres of same radius are placed on H.P touching each other so as the spheres are placed on H.P the line joining the centers is parallel to H.P and given it is perpendicular to V.P so they both align in one line which gives two circles from top view.
