4. A rigid frame in the shape of a right pylamid is made of condet The base ABCD is a square and the apex O is vertically above the centre of the base. The frame is electrically neutral. When it is placed in uniform electric field of intensity E pointing from the corner A wwarde the corner D, total charges induced on the rods DC and OC are known to be q1 and q2 respectively. Now the frame is rotated to make the electric field pointing from the corner A towards the corner C. What ane the charges induced on each rod? D. 2Ecose.

A rigid frame in the shape of a right pyfamid is made of
The base ABCD is a square and the apez O is vertically above the contre
of the base. The frame is electrically neutral. When it is placed in
uniform electric field of intensity E pointing from the corner A towarde
the corner D, total charges induced on the rods DC and OC are known
to be qi and q2 respectively. Now the frame is rotated to make the
electric field pointing from the corner A towards the corner C. What are
the charges induced on each rod?
C.

Transcribed Image Text:4. Total charges induced on each of the edges are
given in the following table.
AB BC CD DA
OA
OB OC OD
-V29, 0
V2q, 0
Hint The electric field along the diagonal is
superposition of the two electric fields each
along the edges. In addition, modulus of induced
charge on a conductor is proportional to the
applied electric field intensity.
