A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of its radius and the height of its conical part is (a) 1\ :3 (b) 1\ :sqrt(3) (c) 1\ :1 (d) sqrt(3)\ :1

A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of its radius and the height of its conical part is 1\ :3 (b) 1\ :sqrt(3) (c) 1\ :1 (d) sqrt(3)\ :1

A solid is hemispherical at the bottom and conical above. If the surface areas of the two parts are equal, then the ratio of radius and height of its conical part is एक ठोस तल पर अर्द्ध गोलाकार है और ऊपर शंक्वाकार। यदि दोनों भागों के पृष्ठ क्षेत्रफल बराबर है, जो उसके शंक्वाकार भाग की त्रिज्या और ऊँचाई का अनुपात है-

A solid is hemispherical at the bottom and conical (of same radius) above it . If the surface areas of the two parts are equal then the ratio of its radius and the slant height of the conical part is

The shape of the lower part of a solid object is like a hemisphere and the upper part like a right circular cone . If the surface area of the two parts be equal , then find the ratio of the length of radius and height of the cone .

A solid is in the shape of a cone mounted on a hemisphere of same base readius. If the curved surface areas of the hemisphere part and the conical part are equal then find the ratio of the radius and the height of the conical part.

The lower and upper part of a solid object are hemispherical and conical respectively. If the area of total surface of 2 parts are equal, then find the ratio of the height of two parts of this object.

U - tube moves with a constant speed parallel to the surface of a stationary liquid. The cross - section area of the lower part of the tube lowered into the liquid, is equal to S_(1) and that of the top part located over the liquid is S_(2) . Friction and formation of waves should be neglect difference in heights at both the openings of the tube. The velocity of the liquid coming out of the top part as seen by an observer on the ground will be
