Where does the centre of mass of a uniform triangular lamina lie?

Define centre of mass. Find the centre of mass of a triangular lamina.

Where does the energy of a capacitor reside.

Give the location of the centre of mass of a (i) sphere, (ii) cylinder, (iii) ring, and (iv) cube, each of uniform mass density. Does the centre of mass of a body necessarily lie inside the body?

Where does growth occur in plants?

What is centre of mass? Show that centre of mass of a system of particles is defined as the point whose position vec is given by vecR = frac(Sigmam_1vecr_)(M)

Where does the endosperm develop form, in an angiosperm?

Where does the formation of acetyl CoA take place in a cell?

Is centre of mass same as the centre of gravity of a body? How can a rigid body be balanced?

Two particles-one of mass m1, and the other of mass m2, carry equal charges. After being accelerated through the same potential difference they enter a region of uniform magnetic field and describe circular paths of radius (r_1) , and (r_2) , respectively. Find the ratio of their masses.

A non-uniform bar of weight W is suspended at rest by two strings of negligible weight as shown in Fig.7.39. The angles made by the strings with the vertical are 36.9^@ and 53.1^@ respectively. The bar is 2 m long. Calculate the distance d of the centre of gravity of the bar from its left end.
