Two square metal plates A and B are of same thickness and material. The side of B is twice that of A. These are connected in series, as shown in Fi. 4.3. Find the ratio `R_(A)//R_(B)` of the resistance of the two plates.

Two square metal plates A and B are of the same thickness and material. The side of B is twice that of A. These are connected as shown in series. If the resistances of A and B are denoted by R_(A) and R_(B) then (R_(A)//R_(B)) is :

Two square metal paltes are of same thichness and material. The side of B is twice that of A. Thses are connected in series, figure. If the resistance of A and B are denoted by R_(A) and R_(B) , find R_(A)//R_(B) .

A and B are two square plates of same metal and same thickness but length of B is twice that of A . Ratio of resistances of A and B is

In the following diagram two parallelopiped A and B are of the same thickness. The arm of B is double that of A. Compare these resistances and find out the value of R_A//R_B is

Two conducting wires A and B are made of same material. If the length of B is twice that of A and the radius of circular cross-section of A is twice that of B, then resistances R_(A)" and "R_(B) are in the ratio

Two planets A and B have the same material density. If the radius of A is twice that of B, then the ratio of the escape velocity V_(A)//V_(B) is
